Question

Using the formula
`Z=(V)/(I)` where V is 220, the current is I, and Z is the impedance, find the current if the impedance is 10-5i watts with steps.

Answer 1

17.6 + 8.8i

Explanation:

Z = V ÷ I

10 - 5i = 220 ÷ I

I = 220 ÷ (10 - 5i)

I = 44 ÷ (2 - i)

I = 44×(2 + i) ÷ (2 - i)(2 + i)

I = (88 + 44i) ÷ (2² + 1²)

I = (88 + 44i) ÷ 5

I = 17.6 + 8.8i
