Question

A 10 ohms resistor, 10 mh inductor, and 10micro farad capacitor are connected in series with a 10khz voltage source. The rms current through the circuit is 0.20A. Find the rms voltage drop across each of the three elements

Answer 1

Answer:

126 V

Explanation:

The computation of the rms voltage is shown below:

=  I × R

=(.2) × (10)

= 2 V voltage drop across capacitor

= I × 1 ÷ (?C)

= I ÷ (2 × pi × f × C)

= (.2) ÷ (2 × pi × 10,000 × 10 × 10^-6)

= .318 V voltage drop across inductor

= I × ?L

= I × 2 × pi × f × L

= .2 × 2 × pi × 10,000 × .010

= 126 V
