Question

question 8: electronics information if a transformer raises the voltage, it will a: raise the resistance b: reduce the resistance c: raise the amperage d: reduce the amperage

Explanation:

According to the principle of power - conservation in a transformer ($P = VI$, where $P$ is power, $V$ is voltage and $I$ is current or amperage), when the power remains constant (assuming an ideal transformer with no power losses). If the voltage $V$ is raised, the amperage $I$ must be reduced to keep the power $P$ the same. Resistance is a property of the circuit elements and is not directly affected by the operation of a transformer in terms of voltage - changing function.

Answer:

D. Reduce the amperage
