# For the circuit what happens if the inductance of the inductor is increased?

AFor this circuit what happens if the inductance of the inductor is increased?

A.   A. The amount of time for the current to reach its maximum value decreases

B.  B.     The maximum current (long after the switch is closed) decreases.

C. C.     The maximum current (long after the switch is closed) increases.

D.   The amount of time for the current to reach its maximum value increases.

Answer: D. The amount of time for the current to reach its maximum value increases.

If the inductance of the inductor of this circuit is increased, the amount of time for the current to reach its maximum value will decrease.

Explain:

An inductor’s voltage is proportional to the rate of change of current through it. This means that an inductor opposes any changes in current and tries to maintain a constant current. Therefore, if the inductance of the inductor is increased, the inductor will resist the change of current more strongly and take more time to reach its maximum value. The maximum current (long after the switch is closed) will not change because it depends on the voltage and the resistance of the circuit.

Based on this information, the correct answer to your question is D. The amount of time for the current to reach its maximum value increases.

FAQs

#### How does the resistance of a circuit affect current flow?

The resistance of a circuit affects the current flow by opposing it. The more resistance there is in a circuit, the less current will flow. The relationship between voltage, current and resistance in a circuit is given by Ohm’s law, which states that voltage is equal to current times resistance. This means that at a constant voltage, the current is inversely proportional to the resistance. The resistance of a circuit depends on the material, length and cross sectional area of the conductors, as well as the temperature.

#### How does the length of a conductor affect resistance?

The length of a conductor affects the resistance by making it directly proportional to it. This means that when the length of a conductor is increased, its resistance increases, and when the length of the conductor is decreased, its resistance decreases. Therefore, the longer the conductor, the more resistance it has, and the less current flows through it. The resistance of a conductor can be calculated by the formula

R = ρl / A

where R is the resistance, ρ is the resistivity, l is the length, and A is the cross-sectional area.

#### How does the cross-sectional area of a conductor affect resistance?

The cross-sectional area of a conductor affects the resistance by making it inversely proportional to it. This means that when the cross-sectional area of a conductor is increased, its resistance decreases, and when the cross-sectional area of the conductor is decreased, its resistance increases. Therefore, the thicker the conductor, the less resistance it has, and the more current flows through it.
