In a closed circuit, if 100 coulomb charges flow for a duration of 50 sec, then the current drawn in the circuit is ________.

Correct option is D

Correct Answer: (D) 2 A

Explanation:

The current (I) in a circuit is calculated using the formula:

​$$I=\frac{Q}{t}$$​​

Where:

• I is the current (in amperes),
• Q is the charge (in coulombs),
• t is the time (in seconds).

Substituting the values:

• Q=100 coulombs,
• t=50 seconds,

​$$I= \frac{100}{50} = 2 \, \text{A}.$$​​

Key Facts:

·         Current is defined as the rate of flow of electric charge through a conductor.

·         The SI unit of current is ampere (A).

·         This formula is derived from Ohm's Law and is fundamental in circuit analysis.

Thus, the current drawn in the circuit is 2 A.
