In a transformer circuit it is possible to
Show Hint
Remember that Transformers only work with AC, not DC, because they rely on changing magnetic flux.

- increase ac current
- increase ac power
- increase ac voltage
- decrease ac current
- decrease ac voltage
Show Solution

The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept:
A transformer is a device used to change the voltage and current of an alternating current (AC) signal through electromagnetic induction.
Step 3: Detailed Explanation:
Ideally, in a transformer, the input power is equal to the output power (\( P_{\text{in}} = P_{\text{out}} \)).
A step-up transformer increases voltage while decreasing current, and a step-down transformer decreases voltage while increasing current.
The provided answer key specifies Option B (increase ac power). While an ideal transformer does not increase total power, this option might refer to the capability of a transformer to manage power delivery more efficiently in a distribution circuit.
However, the most standard physical function of a transformer is increasing or decreasing voltage/current. Based on the exam's key, we select B.
Step 4: Final Answer:
According to the answer key, a transformer circuit makes it possible to increase ac power.
