If a coil of a conductor with 50 Ω resistance is subjected to time varying magnetic field such that the EMF induced is 5 V, then the induced current in the coil is:

Correct option is C

The correct answer is (c) 0.1 A

Explanation:

According to Ohm's Law:

$$I = \frac{V}{R}$$ 

Where,

V = induced EMI = 5V 

R = Resistance = R 50 Ω  

​$$I = \frac{5}{50} = 0.1 A$$ 

So, the induced current is 0.1A.

Information Booster:

• Electromagnetic Induction is the process of generating current through a conductor by changing the magnetic field.

• The induced current depends on the resistance of the coil and the EMF applied.

• Ohm’s Law helps determine current when voltage and resistance are known.

• The direction of induced current follows Lenz’s Law, which opposes the change in magnetic flux.

• The unit of EMF is volt, and unit of resistance is ohm (Ω).

• If resistance is zero, theoretically, current would be infinite, but practically that doesn’t occur due to internal resistances.

• This concept is widely used in generators, transformers, and inductive sensors.
