## Homework Statement

[/B]

Parallel circuit consists of 100ohm resistor with 0.4A current, a 0.47uf capacitor with 0.177A current. Both connected across an AC supply, determine

## Homework Equations

[/B]

The supply voltage

The supply frequency

Current drawn from supply

Power factor of the circuit

The Apparent power

## The Attempt at a Solution

[/B]

The supply voltage is 40V.

Supply frequency is where I am stuck at the minute. I have VL=VC=XC

So VC=1/(2PiFC)

Substitute F for VC and I get VC=1/(2PiC*VC)

F= 1/(2Pi *0.47x10-6*40V)

Doing that equation I get 8465.69Hz which is crazy?

Thanks in advance Alan
