Why the current does not rise immediately in a circuit containing inductance
Text Solution
Verified by ExpertsThe correct answer is:
A
Step 1: In a circuit containing inductance, when a voltage is applied, the inductor opposes any change in current due to its property of inductance.
Step 2: This opposition is presented in the form of an induced electromotive force (emf). According to Lenz's Law, the induced emf will act in such a direction as to oppose the change in current.
Step 3: Therefore, when the circuit is energized, instead of allowing the current to rise immediately, the inductor generates a back emf that impedes the flow of current, creating a delay in its rise.
Step 4: This behavior is characteristic of inductors in AC and DC circuits, where the current does not instantaneously reach its maximum value.
Hence, the correct answer is that the rise of current is hindered because of the induced emf.
