Yes, the EMF of a battery can change with resistors in the circuit. This is because the addition of resistors in a circuit can decrease the amount of current flowing through the circuit, which in turn can decrease the EMF of the battery....
1.The force that makes electrons move to produce an electric current. Electromotive force is supplied by a power source, such as a battery or dynamo. It is measured in volts. 2.The difference in the potential energies of a cathode and anode immersed in the same solution of electrolytes or...
