5. The drop in potential across a resistor is proportional to what? In which direction is there a decrease in potential? Answer the same two questions for a capacitor and

for an emf device.Describe how to analyze resistors in series and in parallel. What if they are in a combination of both series and parallel? Describe the following for both charging and discharging in an RC circuit: the charge on the capacitor, the current in the circuit, the potential difference across the capacitor, and the potential difference across the resistor. Explain how ammeters and voltmeters work. What is a shunt resistor? Why is the internal resistance of a voltmeter an important factor?
