Which of fire extinguisher is used to electrical fire?

There are three types of coil in D.C machine except.

The ______________ resistance is greater the _____________ resistance in single phase induction motor.

The device that used for Winding Continuity test is called:

To measure the current in circuit, you should connect the Ammeter in_______________.

A multimeter reads 4 Ω on running windings and 12 Ω on starting windings, this means that the motor has_____________________________.

Every single phase motor has a rotating part, called the_______, and a stationary part, called the stator.

In electrical ground test for single phase motor with winding, The reading is 1.5 Ohm, so the winding is:

D.C motors convert electrical energy into_____________________.

In electrical insulation test for single phase motor main winding with the auxiliary winding, the reading is 450 Mega ohm so the windings are:

The motor is tripping out at starting, that cause by:

You heard a noise from electrical motor while it’s running in your school, what case this noise?

________________: Make contact between Commutator and output terminals.

In electrical continuity test for starting winding in single phase motor, the reading is 0.2 ohm so the winding is:

The device that used for Insulation Test is called:

In electrical Insulation test for between starting winding and main winding in single phase motor, the reading is 0.9 M ohm so the winding is:

Is a part of the DC Motor?
