9. The following question is about power dissipation in a resistor, which we didnâÂÂt really cover in class. This topic is fairly easy though. In a circuit, all the power delivered by the battery must be dissipated by the elements to the circuit. This is simply a statement of the conservation of energy. How much energy dis- sipated depends on the resistance of the element and the voltage across the resistor, or the current through it. The relevant equa- tions for the problems are as follows. For a circuit element, the power dissipated (or generated) is P = IV, where V and I are the voltage across and current through a circuit element. We know that a resistor obeys OhmâÂÂS Law V = IR, which means that for a resistor, the power dissipated is P = 1R =V²/R. Consider the following two circuits with identical batteries and re- sistors. А В C R R RRS R If the power dissipated by the resistor in circuit A is P, what is the power dissipated by one resistor in circuit B? If the power dissipated by the resistor in circuit A is P, what is the power dissipated by one resistor in circuit C?
