Question

A 8.2 F capacitor is connected to a 120-V, 60-Hz source.

Part A

What is the capacitive reactance of the circuit?

Express your answer using two significant figures.

Part B

How much current is in the circuit?

Express your answer using two significant figures.

Part C

What is the phase angle between the current and the applied voltage?

Express your answer using two significant figures.

Part D

What is the maximum energy stored in the capacitor?

Express your answer using two significant figures.

Part E

What is the power dissipated by this circuit?

Please expain

Explanation / Answer

A) capacitive reactnace, XC = 1/(2*pi*f*C)

= 1/(2*pi*60*8.2*10^-6)

= 323.5 ohms

B) I = V/XC

= 120/323.5

= 0.37 A

C) 90 degrees

d) Umax = 0.5*C*V^2

= 0.5*8.2*10^-6*120^2

= 0.059 J

e) power dissipated = 0
