Question

If the ratio of a transformer 6 to 1 in the applied voltage to the primary is 120 VAC, what is the voltage output from the secondary?

Answer 1

When the ratio of a transformer is 6 to 1 and the primary voltage is 120 VAC, the secondary voltage output will be 20 VAC, as per the transformer equation.

Step-by-step explanation:

If the ratio of a transformer is 6 to 1 and the applied voltage to the primary is 120 VAC, we can use the transformer equation to determine the voltage output from the secondary. The transformer equation states that the ratio of the secondary voltage (Vs) to the primary voltage (Vp) is equal to the ratio of turns in the secondary coil (Ns) to the turns in the primary coil (Np). Here, Np : Ns = 6 : 1 which means for every 6 turns in the primary, there is 1 turn in the secondary.

Applying this, we calculate the secondary voltage using the formula:
Vs = (Ns / Np) × Vp
Vs = (1 / 6) × 120 VAC
Vs = 20 VAC.

So, the voltage output from the secondary is 20 VAC.
