Where Can I Find Resistors

Where would you find a resistor?

Resistors are common elements of electrical networks and electronic circuits and are ubiquitous in electronic equipment. Practical resistors as discrete components can be composed of various compounds and forms. Resistors are also implemented within integrated circuits.

Where can I find resistors in my house?

your find resistor in a serveral thing like LED, Television, Micro oven, hairdryer, tv remote, laptop, computer, and many more things.

What can I use instead of resistor?

A good conductor, such as metal wire, can be used as a Resistor. Resistance can be adjusted by limiting the thickness of the wire or decreasing the path through it. Resistance can be controlled by wire.

What are some examples of resistors?

Examples of Resistors Street Lighting. The street lights get automatically switched on in the evening and switched off in the sunlight. Laptop and Mobile Chargers. Temperature Control. Fan Speed Controller. Measuring Electrical Current. Temperature Sensor. In-Circuit Functioning. Dividing Voltage.

What products contain resistors?

Appliances such as electric heaters, electric ovens, and toasters all use resistors to turn current into heat, then using the heat lost from this resistor to warm the surrounding area.

What do resistors look like?

From the outside, all resistors look more or less the same. As you can see in the top photo on this page, and the one below, a resistor is a short, worm-like component with colored stripes on the side. It has two connections, one on either side, so you can hook it into a circuit.

How are resistors made?

The resistive element is made from a mixture of fine carbon particles and a non-conductive ceramic material. The substance is pressed into a cylindrical shape and baked. The resistance value depends on the dimensions of the body and the ratio between carbon and ceramic material. More carbon means a lower resistance.

Where is the resistor in an electric stove?

The Heating Element or resistor is under the bottom plate in an electric stove, so its heat rises up into the oven area. . . It will have an thermostat, that switches the element On and Off to regulate the oven temperature. . . . There will be other Heating Elements under each of the top hot plate areas.

Can I use a fuse as a resistor?

A fuse limits overcurrent damage by opening the circuit above a certain current value. A fuse can be used as a resistor. There are even fusible resistors, which act as a resistor with a definite value but they also act like a fuse on overcurrent. 2.

How can you increase resistance without a resistor?

add a potentiometer or rheostat to control voltage with variable resistance (high or low) at the power stage of the circuit. heat the circuit during operation to increase overall resistance, cool the circuit to decrease resistance (increased conductivity).

Is a light bulb a resistor?

A resistor or any other device can be a load and a load on the circuit can be a resistor or any other device. A resistor in a circuit is a load. A lightbulb is a resistor that gets hot enough to emitt light.

What are the 4 types of resistors?

Different Types of Resistors – Fixed, Variable, Linear and Non-Linear Resistors & Applications Carbon Composition Resistors. Wire wound Resistors. Thin Film Resistors. Carbon Film Resistors. Metal Film Resistors. Thick Film Resistors. Metal Oxide Resistors. Cermet Oxide Resistors (Network Resistors).

What is resistance in real life?

Resistance is the capacity of a material to resist, or stop, the flow of electrical currents. Resistance readings are measured in ohms (Ω). The optimal resistance for ESD flooring materials is between 1 x 10E5 (100,000 or 1 hundred thousand) and 1 x 10E8 (100,000,000 or 1 hundred million) ohms.

Can a pencil be used as a resistor in a circuit?

Yes, the pencil that we use in our day-to-day activities can be used as a resistor in electrical networks. As compared to other types of resistors this resistor also offers resistance to the flow of electricity through it.

What are series resistors?

When resistors are connected in series, the current through each resistor is the same. In other words, the current is the same at all points in a series circuit. The total resistance of a number of resistors in series is equal to the sum of all the individual resistances.

What are fixed resistors?

The resistors that have a defined value of the resistance are called fixed resistors. The resistance of fixed resistors is not adjustable. The resistance of these resistors does not change with voltage or temperature.

What are the five examples of fixed resistor?

The different types of fixed resistors include: Wire wound resistor. Carbon composition resistor. Carbon film resistor. Metal film resistor. Metal oxide film resistor. Metal glaze resistor. Foil resistor.

Do resistors slow down the current?

From anywhere along the circuit, the resistor will slow the flow of electrons. The second reason to use a resistor is to slow the current flow to a component. Components like LED’s, fans, light bulbs, etc. are designed to function with a certain amount of electrical current.

Why do resistors fail?

A fixed composition resistor normally fails in an open configuration when overheated or overly stressed due to shock or vibration. Excessive humidity may cause an increase in resistance. A variable composition resistor may wear after extensive use, and worn away particles may cause high resistance short circuits.

How are resistors rated?

Resistors are rated by the value of their resistance and the electrical power given in watts, (W) that they can safely dissipate based mainly upon their size.

What does a resistor do in a car?

The blower motor resistor is responsible for controlling the blower motor speed. In the past, this was done by varying the voltage supplied to the blower motor. In newer applications, the blower motor resistor is actually a solid state module that sends a varied signal to the blower motor.

How do you identify a resistor?

Some resistors have contact plates on the bottom. Read the 3 or 4 numbers on the resistor. The first 2 or 3 represent the significant digits and the last indicates the number of 0s that should follow. For example, a resistor reading 1252 indicates a rating of 12,500 ohms or 1.25 kilo-ohms.

Is a battery a resistor?

A battery can be thought of as a perfect voltage source with a small resistor (called internal resistance) in series. The electric energy density produced by the chemistry of the battery is called emf, but the amount of voltage available from the battery is called terminal voltage.

What does a 10K resistor do?

Commonly used in breadboards and perf boards, these 10K resistors make excellent pull-ups, pull-downs, and current limiters. To determine the value of a given resistor look for the gold or silver tolerance band and rotate the resistor as in the photo on the left.
