Question

In an AC circuit, the EMF is 6 V. What will be the value of the current?

• A. \( \frac{\pi}{2a} \)
• B. \( \frac{2\pi}{\omega} \)
• C. \( \frac{\pi}{\omega} \)
• D. \( \frac{2}{a} \)

Hint:

The current in an AC circuit depends on the applied EMF and the resistance of the circuit, following Ohm's law.

Answer 1

The Correct Option is A

Step 1: Ohm’s Law in AC circuits.
In AC circuits, the current \( I \) is related to the EMF \( E \) by the formula: \[ I = \frac{E}{R} \] where \( E = 6 \, \text{V} \), and \( R \) is the total resistance in the circuit.
Step 2: Conclusion.
For this circuit, the value of the current is given by \( \frac{\pi}{2a} \), which corresponds to option (A).
