If the induced EMF in the coil of a conductor of resistance 10 Ω is -2 V, then the induced current in the coil is:

Correct option is A

The correct answer is (a) -0.2A

We can calculate the induced current using Ohm's Law, which relates voltage (V), current (I), and resistance (R) in a conductor:

I= $$\frac{V}{R}$$

Where: I is the current in the conductor (in amperes, A),

V is the induced EMF (electromotive force) in the conductor (in volts, V),

R is the resistance of the conductor (in ohms, Ω).​​

Applying Ohm's Law,

I= $$\frac{-2}{10}$$ = -02.  Ampere

Note-The negative sign indicates the direction of the induced current, which is opposite to the direction of the applied EMF (as per Lenz's Law, which states that the induced current always opposes the change in magnetic flux).
