What happens to the inductance when the current in the coil becomes double?

What happens to the inductance when the current in the coil becomes double its original value? Explanation: ϕ is directly proportional to i. So, when current get double ϕ also becomes double keeping L same. Explanation: L=µ0*N2*A/l, hence as the length of the magnetic circuit l increases, the inductance decreases.

What happens to the inductance when the current in the coil becomes double its original value 1 point becomes half becomes infinity becomes four times remains same?

The inductance is: directly proportional to magnetic field strength, hence as the current value doubles, the inductance also doubles.

How will self inductance L of a coil change when current in the coil is doubled?

When number of turns in a coil is doubled, coefficient of self-inductance of the coil becomes 4 times.

How does self inductance vary with current?

Self-inductance is proportional to the magnetic flux and inversely proportional to the current. However, since the magnetic flux depends on the current I, these effects cancel out. This means that the self-inductance does not depend on the current.

What will happen to the inductance if the number of turns of the coil is decreased?

Number of Wire Wraps, or “Turns” in the Coil All other factors being equal, a greater number of turns of wire in the coil results in greater inductance; fewer turns of wire in the coil results in less inductance.

What is the relation between inductance and flux?

As the inductance of a coil is due to the magnetic flux around it, the stronger the magnetic flux for a given value of current the greater will be the inductance.

When the current in a coil changes from 8A to 2A in time 3×10 2 seconds the emf induced in the coil is 2V The self inductance of the coil is?

When the current in a coil changes from 8A to 2A in 3xx10^(-2)s , th eemf induced in the coil is 2V .

Does the inductance of a coil depend on the current in the coil?

The inductance of a circuit depends on the geometry of the current path as well as the magnetic permeability of nearby materials. Winding the wire into a coil increases the number of times the magnetic flux lines link the circuit, increasing the field and thus the inductance. The more turns, the higher the inductance.

When the number of turns and the length of the solenoid are doubled keeping the area of cross section same the inductance?

When the number of turns and the length of the solenoid are doubled keeping the area of cross-section same, the inductance. L=μ0N2lA. when N and l are doubled. L is also doubled.

What happens to the self-inductance of a coil when current is doubled?

When the rate of change of current is doubled ,emf induced E will also be doubled ,since emf induced is directly proportional to the rate of change of current through the coil .So L (Self inductance) remains constant. 8 clever moves when you have $1,000 in the bank.

What happens when the rate of change of current is doubled?

Originally Answered: The rate of change of a current is doubled in a coil. What is the value of self inductance? When the rate of change of current is doubled ,emf induced E will also be doubled ,since emf induced is directly proportional to the rate of change of current through the coil .So L (Self inductance) remains constant.

What is the rate of change of current through a coil?

In other words, a coil has an inductance, (L) of one Henry, (1H) when the current flowing through the coil changes at a rate of one ampere/second, (A/s). This change induces a voltage of one volt, (VL) in it. Thus the mathematical representation of the rate of change of current through a wound coil per unit time is given as:

What is the relationship between self-inductance and number of turns?

Then the relationship between self-inductance, ( L ) and the number of turns, ( N ) and for a simple single layered coil can be given as: This expression can also be defined as the magnetic flux linkage, ( NΦ ) divided by the current, as effectively the same value of current flows through each turn of the coil.
