How to find the EMF if the resistance is 32 Ohm and the current strength is 0.5 A?

Given:

R = 32 Ohm – resistance of the electrical circuit;

I = 0.5 Ampere – the strength of the current flowing through the electrical circuit.

It is required to determine e (Volt) – electromotive force (EMF).

To determine the electromotive force, you must use the following formula (Ohm’s law):

I = e / R, from here we find:

e = I * R = 32 * 0.5 = 16 Volts.

Answer: the electromotive force is 16 volts.
