A transformer has ten turns of wire on the input side and 50 turns of wire on the output side. If the input voltage is 120 V, what will the output voltage be?

600 V

Explanation:

The transformer equation helps us to calculate the relationship between the ratio of the number of turns of coils in the input and output sources to their respective voltages.

It states that the ratio of the secondary to primary voltages in a transformer equals the ratio of the number of loops in their coils.

Number of input turns/Number of output turns = input voltage/output voltage

10/50 = 120V/output voltage

output voltage = 120 V/0.2

Output voltage = 600 V
