Final answer:
The total power dissipated by resistors in a circuit equals the power supplied by the voltage source, and can be calculated by summing individual power dissipations. Power dissipation is typically higher in parallel circuits than in series circuits for the same voltage source.
Step-by-step explanation:
The question appears to be asking about the power dissipation in electrical resistors within a circuit. According to the conservation of energy principle, the total power dissipated by resistors in a circuit is equal to the total power supplied by the source. Therefore, if we are given individual powers dissipated by resistors, such as P1, P2, and P3, the total power would be the sum of these individual powers (P1 + P2 + P3).
One formula that is useful for finding the power dissipated by a resistor is P = IV, where P is power, I is current, and V is voltage. This can also be expressed in terms of resistance (R) and voltage using the formula P = V^2/R when the current is not known directly but the resistance and voltage across the resistor are known.
In the provided information, various power dissipation examples are given, and in all cases, they follow the same principle where the power dissipated equals the power supplied. It's important to note that power dissipation in parallel circuits will typically be greater than in series circuits when connected to the same voltage source.
