RULES OF A PARALLEL CIRCUIT
components are connected in multiple pathways for the current to follow
Total Voltage in a parallel circuit has the same value as the voltage across each branch (V)
Total Current in a parallel circuit is the Sum of the individual branch currents (I)
Total Resistance of a parallel circuit is always less than any of the individual resistance values
