Question 138: Electromagnetic Induction

Question

An ideal coil of $$10H$$ is connected in series with a resistance of $$5\Omega $$ and a battery of $$5V$$. $$2$$ second after the connection is made, the current flowing in ampere in the circuit is

Accepted Answer

KEY CONCEPT :
$$I = {I_0}\left( {1 - {e^{ - {R \over L}t}}} ight)$$
(When current is in growth in $$LR$$ circuit)
$$ = {E \over R}\left( {1 - {e^{ - {R \over L}t}}} ight)$$
$$ = {5 \over 5}\left( {1 - {e^{ - {5 \over {10}} 	imes 2}}} ight)$$
$$ = \left( {1 - {e^{ - 1}}} ight)$$

Answer

$$\left( {1 - {e^{ - 1}}} \right)$$

Answer

$$\left( {1 - e} \right)$$

Answer

$$e$$

Answer

$${{e^{ - 1}}}$$
