Winding Inductances Quiz

What is inductance?

• Ability to store electric charge

• Resistance to flow of electricity

• Opposition to change in voltage

• Opposition to change in current

Define inductance in your own words.

• Causes changes in current flow

• Has no effect on current flow

• Opposes changes in current flow

• Increases the speed of current flow

What are the factors that affect inductance?

• Type of insulation, weight of the wire, diameter of the wire, resistance

• Voltage, current, frequency, resistance

• Color of the wire, temperature, length of the wire, resistance

• Number of turns, cross-sectional area, core material, nearby magnetic fields

Name two factors that can affect the inductance of a coil.

• Temperature and pressure

• Color and weight

• Voltage and current

• Number of turns and core material

How do you calculate inductance in a coil?

• L = (μ * N^2 * A) / l

• L = (μ * N * A) * l

• L = (μ * N * A) / l

• L = (N^2 * A) / l

Explain how to calculate the inductance of a coil.

• L = (μ * N^2 * A) / l

• L = (μ * N^2 * A) / V

• L = (N^2 * A) / l

• L = (μ * N * A) / l

What is mutual inductance?

• The phenomenon where a changing current in one coil induces a voltage in an adjacent coil.

• The ability of a coil to store energy in the form of a magnetic field.

• The resistance of a coil to changes in current flow.

• The process of inducing a current in one coil by changing the voltage in an adjacent coil.

Describe what mutual inductance means.

• Mutual inductance is the ability of a coil to store energy in the form of a magnetic field

• Mutual inductance is the phenomenon where a changing current in one coil induces a voltage in an adjacent coil.

• Mutual inductance is the resistance to the flow of current in a coil

• Mutual inductance is the process of converting electrical energy into mechanical energy

What is self-inductance?

• The inherent ability of a circuit to oppose the change in current flowing through it.

• The ability of a circuit to store energy in the form of a magnetic field

• The ability of a circuit to conduct electricity without resistance

• The ability of a circuit to increase the current flowing through it

Explain the concept of self-inductance.

• Opposing the change in current flow by creating a magnetic field

• Having no effect on the change in current flow

• Preventing the change in current flow by creating a magnetic field

• Assisting the change in current flow by creating a magnetic field
