Final answer:
To calculate the total energy delivered to a circuit element, multiply the charge moved by the voltage. For instance, a 12.0 V battery moving 5000 C of charge provides 60,000 J of energy. Energy conservation in circuits is crucial, making sure energy supplied equals the energy dissipated plus any energy stored in magnetic fields.
Step-by-step explanation:
To calculate the total energy delivered to a circuit element, you use the formula PE = qV, where PE represents the potential energy, q is the electric charge that has moved, and V is the voltage. For instance, if we have a 12.0 V motorcycle battery that moves 5000 C of charge, the total energy delivered by the battery is calculated by multiplying the charge by the potential difference, which in this case results in 5000 C * 12.0 V = 60,000 J. Similarly, a 12.0 V car battery that moves 60,000 C of charge would deliver 720,000 J of energy. It's important to ensure that energy is conserved in the circuit; energy supplied by the source equals the sum of energy dissipated by all resistors and, if applicable, the energy stored in the magnetic field of any coils in the circuit.
