A model electric train requires a low voltage to operate. If the primary coil of its transformer has 400 turns, and the secondary has 40 turns, how many volts will power the train when the primary is connected to a 120-volt household circuit?
To calculate: the voltage of a train in a transformer for given information
Answer to Problem 56A
The voltage on secondary coil is
Explanation of Solution
Given:
Primary coil
Secondary coil
Voltage on primary winding
Formula used:
Calculation:
The relation between voltage and number on turns on primary and secondary coil is,
The equation becomes
The voltage on secondary winding is
Conclusion:
From a relation between the number of turns and the voltage ratio, the voltage on secondary coil is calculated as
