Complex numbers are used to describe current I, voltage E, and impedance Z (the opposition to current).

Question:

Complex numbers are used to describe current I, voltage E, and impedance Z (the opposition to current). These three quantities are related by the equation E = IZ, which is known as Ohm’s Law.

Thus, if any two of these quantities are known, the third can be found. In each exercise, solve the equation E = IZ for the remaining value.

I = 20 + 12i, Z = 10 –5i
