A: This may seam odd, but the different length of screwdriver really doesn’t affect the torque directly. Torque is the force applied times the distance from the axis you are rotating about. The long handle will move your hand further from the rotation and give you more torque.

Why do we prefer screw driver having long arms?
Torque or turning effect due to a force is maximum when r is maximum. We prefer to use a wrench with long arm because when the length of the arm(r) is long, the force (F) required to produce a given turning effect ( x ) is smaller. Hence, a nut can be unscrewed easily.
Why is it easier to turn a screw with a long screw driver?
Long screwdrivers are easier to turn because the grip is in the palm of the hand, thus allowing all fingers to contribute. A shorter screwdriver is turned with the thumb and first two or three fingers, providing much less torque.
