The function generator being used as a source for an AC circuit gives a time dependent voltage that can be written as:
V=0.070vsin(4000t)
1) What is the angular frequency?
2) What is the frequency?
3) What is the peak voltage?
4) What is the rms voltage?
5) If the voltage source is hooked up to a circuit in which the only element is a 400 ohm resistor, what is the peak current?
6) If the voltage source is hooked up to a circuit in which the only element is a 6microfarad capacitor, what is the peak current?
7) If the voltage source is hooked up to a circuit in which the only element is a 0.3H inductor, what is the peak current?
