Question

Study the following electric circuit diagram and answer the questions that follow:

1. What does the circuit diagram shows?
2. What will happen if the direction of current is reversed? Justify your answer giving circuit diagram.

Answer 1

1. The circuit diagram shows Oersted’s experiment, demonstrating the magnetic effect of a current-carrying conductor, where the compass needle exhibits deflection due to the magnetic field generated by the flowing current in the circuit.
2. The compass needle will deflect in the other direction if the current is flowing in the opposite way. This is due to the fact that reversing current causes the wire's magnetic field to reverse direction.
