(a)
To find: The relation between input power to primary coil and power output of the secondary coil in a transformer.
(a)
Explanation of Solution
Introduction:
In an ideal transformer, by conservation of energy, there is no loss of energy.
In an ideal transformer, there is no loss of energy. Hence, input energy = output energy. Power is directly proportional to energy. Hence, input power in primary coil is equal to output power of the secondary coil.
Conclusion:
Input power of primary coil is equal to output power of secondary coil.
(b)
To find: The relation of product of voltage and current in the primary with the product of voltage and current in the secondary coil.
(b)
Explanation of Solution
Introduction:
Product of voltage and current is known as power.
In an ideal transformer, input power in primary coil is equal to output power of the secondary coil. Hence, product of voltage and current of primary coil is equal to product of voltage and current of the secondary coil.
Conclusion:
Product of voltage and current of primary coil is equal to product of voltage and current of the secondary coil.
