Q2. EXPLAIN THE CONSTRUCTION AND
Oksi-84 [34.3K]

Answer:

The working of an electric motor is based on the assumption that a conductive current generates a magnetic field around it. Consider the following situation,

Take two bar magnets, and leave a small space between the poles facing each other. Now, take a small conductive wire length and make a loop. Keep this connection between the magnets, so that it is still inside the magnet’s area of influence. Now for the final part. Attach loop ends to battery terminals.

As electricity flows through your simple circuit, you will find that your loop “moves.” The magnet’s magnetic field interferes with that generated by the conductor’s electrical current flow. Because the loop has become a magnet, it will draw one side of it to the magnet’s north pole, and the other to the south pole. That causes the loop to rotate continuously. This is the idea of an electric motor working.

What is current of 12 ohm? help me pleasee​
Ne4ueva [31]

Answer:

Current for 12 ohms = 2.5

Explanation:

Ohm's Law:

Voltage = IR

Current = V/R

Resistance = V/I

Therefore, current = 30V/12 Ohms

30/12 = 2.5

So current for 12 ohms = 2.5

I hope this helps :>

Rotor windings in wound rotor motors are connected to ? on the shaft of the motor. Brushes allow those windings to be connected
Mashutka [201]

Answer:

Slip Rings

Explanation:

The wound rotor motor has a three-phase winding with each one connected to seperate slip rings. These slip rings contain brushes which form a secondary circuit where resistance can be inserted and this will allow for the rotor current to run more in phase with the stator current which will result in increased torque that is created
