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 = 10 + 4i, E = 88 + 128i
