Capacitors

Q1:

What is the impedance of this circuit?

A 5928

B 2000

C 1902

D 1798

ANS:A - 5928

Impedance Cannot be Directly Measured, We Need to find Xc first. So, Xc = 1/2πfC. Xc = 1/( 2 x 3.14 x 5000 x 0.01 x 10-6 ). Xc = 3184.7. Z = Sqrt( Xc2 + R2 ). Z = Sqrt( 3184.72 + 50002 ). Z = 5928 Ω.
