In your physics lab, you are given a hand generator and an assortment of wires with different values of resistance. You connect the leads of the generator across each wire in turn, and in each case attempt to turn the generator handle at the same constant rate. You find that you must push harder on the handle when the leads of the generator are connected _______.
Solution
1) when generator handle rotates at the same constant rate the emf voltage will be same for eah resistance but when connected with lowest resistance its produced more power hence for rotating the handle more power is required or we can say that we required harder push with lowest resistance
2) Turning of handle at constant rate produced constant voltage across the connected wire
3) Turning of handle at constant rate become harder because a greater current through connected wire.
