A student uses a transformer to increase the voltage of a low-voltage electrical current. Which part of the transformer uses electromagnetic induction?
Q1. A student uses a transformer to increase the voltage of a low-voltage electrical current. Which part of the transformer uses electromagnetic induction?
Answer: Primary coil to increase voltage
Explanation: The primary coil uses electromagnetic induction to increase the voltage, as it induces a higher voltage in the secondary coil, whereas the other options describe different components or functions in a transformer.
