The resistance of the voltmeter is R = 6 kOhm. What charge will pass through the voltmeter during t = 2.0 minutes if it shows a voltage of U = 90V.
q = I * t, where q is the electric charge, I is the current in the circuit, and t is the charge transfer time.
I = U / R, where U is the voltage, and R is the resistance in this section of the circuit.
q = It = (U * t) / R = (90 W * 2 min) / 6 kΩ = (90 W * 120 s) / 6000 Ohm = 10800/6000 = 1.8 Cl.
Answer: q = 1.8 Cl.
