RMS voltage, phase angle, AC circuits

[kevinlikesphysics]

Homework Statement

An AC power supply with a peak volatge output of 200 volts, operating at 60 Hz, is connected to a 53 microFurad capacitor

A) what is the difference in phase angle between the applied voltage and the current

B) what is the rms current in the circuit

C) what is the rate of energy dissipated to heat in the capacitor

Homework Equations

Several,

The Attempt at a Solution

I really just need an explanation of phase angle and what RMS is. The other stuff I have equations for and seems pretty straight forward.

Any information or links about phase angle and its use/purpose/definition would be greatly appreciated.

hi kevinlikesphysics!

rms voltage is peak voltage divided by √2

phase angle is the difference in phase between the https://www.physicsforums.com/library.php?do=view_item&itemid=301" in AC circuits) …

in this case, you should be able to get it from the basic https://www.physicsforums.com/library.php?do=view_item&itemid=112" equation relating voltage and charge (remember, current = charge per time )
