When using Ohm's law to determine the applied voltage of a parallel circuit in which the value of the circuit amperage and resistance are known, the formula used would be ____.
A) R = I * E
B) I = E * R
C) E = I * R
D) I = E / R

Ohm's law states that voltage (E) is equal to the product of current (I) and resistance (R), E = I * R. Therefore, to determine the applied voltage of a parallel circuit when I and R are known, we would use the formula E = I * R.
