DC Circuits Simplest circuit – Continuous flow of charge in the circuit (charge is conserved). –PE gained in battery = PE lost in the resistor – Voltage raised by battery = Voltage drop across the resistor Resistors connected in series R + I V IR V = R 1 R 2 + + = 2 1 R R R S same current through each resistor
