Two squares of copper are separated by 6 x 10-6 meters and have a capacitance of 8 nF. (Only air is between the squares.) A) What is the area of each plate? The plates are connected to a 120 V power source. B) What is the charge on the plates? C) What is the potential energy stored in the capacitor? D) What is the magnitude of the electric field between the plates? The capacitor is now removed from the 120 V source and replaced with a 1000 Ohm resistor. E) How much current flows through the circuit? f) How much power is being dissipated by the resistor? If the resistor is made of copper (ρ = 1.68 x 10-8 Ωm) of length 0.050 m. G) What is the cross sectional area of the resistor?

1,The same voltage is applied between the plates of two
different capacitors. When used with capacitor A, this voltage
causes the capacitor to store 15 μC of charge and 3.4 x 10-5 J of
