Voltage is the same across each device Ohm's Law applies separately to each branch Total current is the sum of the branch currents Equivalent (total) resistance decreases as the number of branches increases Equivalent (total) resistance of 2 equal resistances is half the individual resistance Equivalent (total) resistance of 2 parallel branches is less than the smallest resistance Overloading Home circuits connected in parallel Total current increases as each device is added Total energy supplied increases as each device is added short circuits fuses &amp; circuit breakers Compound Circuits Equivalent resistance Applying Ohm's Law total current separate components Labs &amp; Demos: Activity - Series &amp; Parallel Circuits: You construct series and parallel circuits using light bulbs and observe characteristics of the circuits.
