Is the statement true or false: Electrical current will flow in transformers?

The statement that electrical current will flow in transformers is actually true. In transformers, alternating current (AC) is used, and this current flows through the primary winding, generating a magnetic field that induces current in the secondary winding. This process is fundamental to how transformers operate, as they rely on electromagnetic induction to transfer electrical energy from one circuit to another, typically at different voltage levels.

While a transformer does not allow direct current (DC) to pass through it efficiently (DC does not create a changing magnetic field, which is necessary for the operation of a transformer), the use of alternating current is what enables a transformer to function. Therefore, to clarify, the answer is not consistent with the operational principles of transformers.

In summary, the correct understanding centers on the fact that transformers are designed to operate with alternating current, which flows in them due to the alternating magnetic fields created. The assertion that the statement is false does not align with the fundamental principles of how transformers are meant to work.
