Homework Statement



An LRC series circuit with R = 200!, L = 32mH, and C = 2.5μF is
powered by an ac voltage source of peak voltageV0 = 200V and frequency
f = 770Hz. Determine the peak current that flows in this circuit.


Homework Equations



V= IR

-L dI/dT +Q/C = 0

w = 2 pi f

The Attempt at a Solution

Hi bgav88,

Homework Statement



An LRC series circuit with R = 200!, L = 32mH, and C = 2.5μF is
powered by an ac voltage source of peak voltageV0 = 200V and frequency
f = 770Hz. Determine the peak current that flows in this circuit.


Homework Equations



V= IR

-L dI/dT +Q/C = 0

w = 2 pi f
What's the relationship between peak current and peak voltage for an AC circuit?

(For a DC circuit you would use Ohm's law; what similar equation applies here?)
