What is the inductive reactance in a circuit with a .5 H inductor in a circuit supplied by 110 V 60 Hz power?

2pie x 60 x .5 = 188.5

If the voltage drop across in a doctor exceeds_____Then there is an open

5%

What is the inductive reactants in a circuit with a .012 Henry and Dr. in a circuit supplied by 32 V DC power

6.28x 0x .012= 0

If current flows from left to right in a straight wire, and looking into the right end of the wire, the current magnetic rings will rotate

Clock wise

And induced voltage that opposes the applied voltage is called

Counter electromotive force

For internally shorted inductor windings, you should look for

Discoloration overheating

When power is remove from motor field or breaks, the stored energy needs to be

Dissipated

The Silla annoyed confines all that's magnetic lines of flux within the core

False

When testing AC solenoids, the core must be removed

False

The unit of measurement for inductance is called the

Henry

The result of combining resistance in reactants in a circuit is called

Impedance

If the number of turns is increased in a coil, then the inductance will

Increase

As frequency increases, then inductive reactance

Increases

If the inductance in a circuit increases, then the inductive reactance

Increases

The unit of measurement for inductance is represented by the letter

L

One can tell the direction of magnetic field rotation by using the

Left hand rule

When using an ohm meter to measure between the windings Ankor, a reading above_____Is an indication the inductor is good

One mega Ohm

When using a Megger to measure between the windings in the core, a reading above_____Is in in dictation the inductor is good

One megaohm

The ease with which material passes magnetic lines of flux is termed

Perm ability

When using a Megger, the inductor must be_____From the circuit

Removed

When a coil of wire cannot increase its magnetic flux with increases in current, it is said to have reached____

Saturation

One________ _________Is the measure of time it takes for current in in a doctor to reach 63.2% of its final value

Time constant

Not affect can't be reduced by adding and a doctor at the AC input selection of a solid-state drive

True

The greater the inductance in the DC break circuit, the greater the time delay when denergizing the brake

True
