Question

For a certain driven series RLC circuit, the maximum generator emf is 156 V and the maximum current is 3.32 A. The current leads the generator emf by 0.959 rad. (a) What is the impedance of the circuit?

Answer 1

Answer:

Z=76.6 + j46.7

Explanation:

angle between Voltage and current: ∅=0.959

Impedence is given by:

V=IZ

Z= V/(Icos∅ + j Isin∅)

Z= 156/(3.32 ∠ 0.96)

Z=76.6 + j46.7
