a.
The cost per kWh to operate the radio.
a.
Answer to Problem 82A
Explanation of Solution
Given:
The potential supplied by the battery,
The current through the circuit,
The cost of the battery,
The time for which the battery works,
Formula used:
The energy
Where,
I is the current and V is the potential difference.
Calculation:
Using the above formula, the energy delivered by the battery,
Then the cost per kWh to operate the radio will be,
Conclusion:
Hence, the cost per kWh to operate the radio is
b.
The new cost per kWh to operate the radio if cost is
b.
