(c)
The potential difference across the battery.
(c)
Answer to Problem 50A
The potential difference across the voltage is 18.5 V.
Explanation of Solution
Given:
Reading of ammeter is
Resistance is
Resistance is
Voltage drop across the 15
Voltage drop across the 22
Formula:
The expression for potential is given by
Here,
Calculation:
The battery voltage is equal to the sum of the voltage drop across the individual resistor. The sum of the voltage drop across the two resistor is 11 V +7.5 V = 18.5 V.
Conclusion:
Hence, the required potential difference across the voltage is 18.5 V.
