# Which best contrasts an electric motor?

Contents

Which best contrasts an electric generator and an electric motor? A generator converts kinetic energy to electrical energy, and a motor converts electrical energy to kinetic energy.

## Which best compares a brush and a computer in an electric motor?

Answer Expert Verified. Answer: A brush and commutator in an electric motor both of them carry electrical current from a power source. Therefore, option B is correct that is both carry electrical current from power source.

## Which reverses the flow of current through an electric motor?

Commutator reverses the flow of current through an electric motor!

## In what ways is electric motor different from an electric motor?

What are the Differences between Electric Motor and Electric Generator?

Basis Electric Motor Electric Generator
Function It converts electrical energy into mechanical energy. It converts mechanical energy into electrical energy.
Current The current is supplied to armature windings. The current is produced in armature windings.

## How would this change affect the electric current?

A switch is closed, so the circuit would be incomplete and broken and the lights in the circuit would not shine. A switch is closed, so the circuit would be complete and unbroken and the lights in the circuit would shine.

## What contrasts better electric motor or electric generator?

Which best contrasts an electric generator and an electric motor? A generator converts kinetic energy to electrical energy, and a motor converts electrical energy to kinetic energy.

## How long can a brushless motor run continuously?

If you are looking for a motor with a long life expectancy, consider a brushless motor. Brushed motor life is limited by the brush type and can attain 1,000 to 3,000 hours on average, while brushless motors can attain tens of thousands of hours on average, as there are no brushes to wear.

## What is required for an electric current to flow?

To produce an electric current, three things are needed: a supply of electric charges (electrons) which are free to flow, some form of push to move the charges through the circuit and a pathway to carry the charges. … The flow of electricity can be likened to a flow of water through a pipe.

## How does a commutator work in an electric motor?

The commutator itself is a split ring, typically made of copper, with each segment of the ring attached to each end of the armature coil. … As the brushes pass over the gaps in the commutator, the supplied electrical charge switches commutator segments, which switches the electrical polarity of the armature coils.

## Which device manages the flow of current in an electric circuit?

the flow of current in an electric circuit can be managed by a switch.

## How do you make an electric motor more powerful?

We can increase the turning force (or torque) that the motor can create in three ways: either we can have a more powerful permanent magnet, or we can increase the electric current flowing through the wire, or we can make the coil so it has many “turns” (loops) of very thin wire instead of one “turn” of thick wire.

## What are electric motors used for?

An electric rotor. An electric motor is a device used to convert electricity into mechanical energy—opposite to an electric generator. They operate using principles of electromagnetism, which shows that a force is applied when an electric current is present in a magnetic field.
