You create a circuit with three resistors and a battery. If you add up the power dissipated through all three resistors, what must it equal? Does your answer depend on how you have combined your resistors?
The sum of power dissipated by the three resistors and whether it depends on the combination of resistors.
Answer to Problem 1CQ
The sum of power dissipated by the three resistors is equal to the total power consumed.
Explanation of Solution
Power dissipated by the resistors are nothing but heat losses. Power dissipated is additive. This means the sum of power dissipated by the three resistors gives the total power.
When the resistors are connected in series or parallel combination, only the effective resistance changes. However, the total power equals the power dissipated by the individual resistors since the dissipation is by means of heat loss only.
