Question

Give relation between output power and input power for an ideal transformer.Answer the given question in brief.

Answer 1

Explanation:

If ideal and no losses then the output power is equal the input power. But depending on the primary to secondary turns ratio the output voltage will be directly this ratio, step up or down, and the current will be inverse to the ratio.

Answer 2

Answer:

Explanation:

An ideal transformer is considered to be one that has -

- no copper losses and no winding resistance

- no iron loss the in core  and no leakage flux

Thus, an ideal transformer provides precisely the same output power as the input power. An idea transformer's effectiveness is 100%. In reality, it is actually difficult to have such a transformer, but the ideal transformer model makes the problems easier. If it is ideal and there is no losses then the output power is equal to the input power.

However, depending on the primary to secondary turns ratio, the output voltage will be directly dependent on the ratio, be it step up or down, and the current will be inverse to the ratio.
