Question

The voltage across the input terminals of a transformer is 110 V. The primary has 50 loops, and the secondary has 25 loops. The voltage the transformer puts out is

Answer 1

The output voltage of the transformer with an input of 110 V, and primary and secondary coils having 50 and 25 loops respectively, is 55 V.

Step-by-step explanation:

The question asks for the output voltage of a transformer when the input voltage is 110 V, the primary coil has 50 loops, and the secondary coil has 25 loops. According to the principle of a transformer, the output voltage can be calculated using the ratio of the number of turns in the primary coil (Np) to the number of turns in the secondary coil (Ns), which is given by the formula Vs = (Ns/Np) * Vp. Given that Ns = 25, Np = 50, and Vp = 110 V, the output voltage (Vs) can be found as follows:

Vs = (25/50) * 110 V = 0.5 * 110 V = 55 V.

Therefore, the transformer puts out an output voltage of 55 V.
