Parallel

• each component is individually connected to the power supply in its own loop - this means that the potential difference is the same across each component
• the total current through the circuit is the sum of the currents through each branch/loop of the circuit
• the total resistance of two components in parallel is less than the smallest resistance from individual components
• switching individual loops (circuits) in parallel on/off will not affect other loops (houses are wired with parallel circuits so that we can turn differences appliances on/off separately from each other).
