Topic hierarchy

20.1: Overview
An electrical circuit is an interconnection of electrical elements that has a closed loop giving a return path for the current.
20.2: Resistors in Series and Parallel
The total resistance in the circuit with resistors connected in series is equal to the sum of the individual resistances.
20.3: Kirchhoff’s Rules
Kirchhoff’s circuit laws are two equations that address the conservation of energy and charge in the context of electrical circuits.
20.4: Voltmeters and Ammeters
Voltmeters and ammeters are used to measure voltage and current, respectively.
20.5: RC Circuits
An RC circuit has a resistor and a capacitor and when connected to a DC voltage source, and the capacitor is charged exponentially in time.
