(a)
To calculate: the AC voltage available in secondary coil.
(a)
Answer to Problem 58A
The voltage in the secondary coil is
Explanation of Solution
Given:
Number of turns on primary coil
Number of turns on secondary coil
Voltage on primary coil
Voltage in secondary coil
Formula used:
Calculation:
The relation between voltages and number on turns on primary and secondary coil is,
The equation becomes,
The voltage in secondary coil is
Conclusion: The voltage in secondary coil is
(b)

(b)
Answer to Problem 58A
The current in the
Explanation of Solution
Given:
Voltage in the secondary coil
Resistance in secondary circuit
Formula used:
Calculation:
Ohm’s law states that in any electric circuit the current is directly proportional to voltage and inversely proportional to resistance.
Mathematically,
The current in the
Conclusion:
The current in the circuit is
(c)
To calculate: the power supply in the primary circuit.
(c)
Answer to Problem 58A
The power is
Explanation of Solution
Given:
Voltage in the primary coil
Current in secondary circuit
Formula used:
Power into the primary coil is equal to the Power out from the secondary coil. And the formula of the Power is given by the relation between voltage and current. Measured in watts(W).
Mathematically,
The power supplied to the primary circuit is
Conclusion:
By the concept of the power out from the secondary coil to the primary coil, the power calculated as
