A 500 ohm resistor in series with a 3.00 μF capacitor is connected to a 12.0 Volt (peak) 120 Hertz AC power supply.
a) Find what is the reactance?
b) Find what is the total impedance?
c) Find the phase difference between current and voltage (which leads?)
d) Find how much power is dissipated in the resistor?
Identical point charges of +3.6 C are fixed to diagonally opposite corners of a square. A third charge is then fixed at the center of the square, such that it causes the potentials at the empty corners to change signs without changing magnitudes.
