Question

Angela is an electrical engineer who is testing the voltage of a circuit given a certain current and resistance. she uses the following formula to calculate voltage:

the circuit she tests has a current of 3 + j 4 amps and a resistance of 4 - j 6 ohms.

what is the voltage of the circuit?

Answer 1

The Voltage of the given Circuit is gotten as; V = 36 - 2j Volts

How to multiply Vectors?

We are given;

Current; I = 3 + 4j amps

Resistance; R = 4 - 6j ohms

From ohms law, we know that;

V = IR

Thus;

V = (3 + 4j) * (4 - 6j)

V = 12 + 16j - 18j - 24j²

Now, in vector notation; j² = -1. Thus;

V = 12 - 2j + 24

V = 36 - 2j Volts
