Hi, Here's my question. 26.45: An emf source (e=120 V), a resistor (R=80.0 W), and a capacitor (C=4.00 mF) are connected in series. As the capacitor charges, what is the magnitude of the charge on each plate of the capacitor when the current in the resistor is 0.900 A? Hint: From the information given, first calculate the voltage across the capacitor when the 0.900 A current flows in the circuit. Then use the voltage as a function of the time equation for a charging capacitor in an R-C circuit.
