What will be the effect if the d.c motor is directly connected across the supply without starter?

At zero rpm a dc motor draws a current that could be enough to blow the circuit breaker. In that case it is normal to place a resistor in series to limit the current to slightly below the circuit-breaker setting. The resistor is switched out after the motor runs up.


What allows the current to enter the electronromagnet in an electric motor?

The resistor allows current to enter the electromagnet in an electric motor. The resistor regulates the amount of current that enters the electric motor.


Why is generator armature harder to rotate when it is connected to a circuit and supplying electric current?

Because a generator extracts energy from whatever is rotating it and passes this (by the electric current it produces) down the circuit to the motor (or light bulb or heater) where it is used. When there is no complete electric circuit, no electricity can flow so no (little) energy is extracted, but when the circuit is closed, electricity does flow and the armature is more difficult to turn.

If you have a DC passing through a circuit will the current decrease when you add a DC motor and if so by how much?

In the circuit where the DC motor is added, it was not specified whether the motor was added in series or in parallel to circuit elements. If it was added in series, it will increase circuit resistance and it will cause circuit current to go down. In parallel, the motor will reduce total circuit resistance, and circuit current will increase.

Why do the bulbs dim when the refrigerator turns on?

The refrigerator has a motor load within it. When the refrigerator starts it draws a high current. This high starting current draws the voltage down until the refrigerator's motor (compressor) gets up to speed. A refrigerator is an appliance that should be on a dedicated circuit. This means that no other electrical devices should be connected to the refrigerators circuit. If the lights are dimming, then the refrigerator is on the same circuit as the lights.

What are examples of a load in a circuit?

Any specific device that draws a current which is connected within the circuit is an example of a circuit load. That may be a resistance and a loudspeaker LED computer and induction motor or whatever which can withdraw the energy from the output.

Why current is supplied to DC motor?

What supplies a dc motor is not current, but voltage. Current is what flows in the circuit formed by the dc motor and for the charge. That current varies according to the resistance of the circuit.

Why is a motor needed in a circiut?

A motor is not needed in a circuit, a motor is an electrical load for the current to drive, but the circuit can perform with other types of load - such as a lamp, a transformer, a heating coil, or any electronic load. if you mean 'why does an electric motor need a circuit?' this is because the motor is an electrical device which has coils of wire to produce a magnetic field, without the circuit it cannot function.

Is there a method to control a dc motor speed by simple circuit?

The easiest way to control any electric current to any device is with the inline use of either a manual or electric reistate.
