The current ( I ) in an electrical circuit is directly proportional to the voltage applied ( E ) and inversely proportional to the circuit impedance.
A) $I = \frac { Z } { E }$
B) $E = \frac { V } { I }$
C) $I = \frac { E } { Z }$
D) $I = \frac { E ^ { 2 } } { Z }$

This follows Ohm's law, which states that I = V/Z, where V is the voltage and Z is the impedance. By manipulating the equation, we can get I = E/Z. Therefore, option C is the best choice.

The Current ( I ) in an Electrical Circuit Is I=ZEI = \frac { Z } { E }I=EZ​
