Question

(1)(A)Determine the electric field strength between two parallel conducting plates to see if it will exceed the breakdown strength for air (3 ✕ 10⁶ V/m).The plates are separated by 2.72 mm and a potential difference of 4840 V is applied? How close together can the plates be with this applied voltage without exceeding the breakdown strength?

(B) FInd the total capacitance of the combination of capacitors (C₁ = 0.310 µF, C₂ = 22.5 µF.)

(C)585 C passes through a flashlight in 0.590 h. What is the average current?

(D)A current of 3.7 A flows through a wire. Determine the number of electrons per second passing a given point in the wire.
