What is the voltage on the secondary side of a transformer with a primary voltage of 120 volts and 4000 turns on the secondary side?

To determine the voltage on the secondary side of a transformer, you can use the transformer equation that relates primary voltage, secondary voltage, primary turns, and secondary turns. The equation is:

( V_p / V_s = N_p / N_s )

where ( V_p ) is the primary voltage, ( V_s ) is the secondary voltage, ( N_p ) is the number of turns on the primary side, and ( N_s ) is the number of turns on the secondary side.

In this case, you're given a primary voltage of 120 volts and a secondary winding with 4000 turns. To find ( V_s ) (the secondary voltage), you also need to know the number of turns on the primary side. Typically, if it's not specified, we can assume a common scenario where the primary side has fewer turns, often around 100 turns for household applications.

Let's assume the primary side ( N_p ) has 100 turns. Here's how you would calculate the secondary voltage ( V_s ):

1. Set ( V_p = 120 ) volts and ( N_s = 4000 ) turns.

2. You would set ( N_p = 100 ) turns.
