Figure 18.8 (Quick Quizzes 18.5 and 18.6)

To determine
The power delivered to R1 when the switch is open.

Explanation

Given Info: The power delivered to the resistor R1 when the switch is closed is Pc . The power delivered to the resistor R1 when the switch is open is Po .

Explanation:

The expression of power is,

Po=V2R1

  • Po is the power dissipated by the resistor when the switch is open,
  • V is the potential across the resistor,
  • R1 is the resistance of the resistor 1,

When the switch is closed, resistor R1 and R2 are in parallel fashion with the power supply.

Conclusion:

When the switch is open the potential across the Resistor R1 is the potential across the power supply
