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

When there is current drawn, the Terminal Voltage ( V A-V B ) is less than the EMF due to the batterys internal resistance ( r) + + = 2 1 1 1 1 R R R P Ir IR = Terminal voltage V A V B EMF same potential difference across each resistor R 1 R 2 Internal resistance of battery + A B R r I...
