An alternator works together with the battery to supply power for the electrical components of the vehicle. The output of an alternator is direct current (DC). When the alternator pulley is rotated, alternating current (AC) passes through a magnetic field and an electrical current is generated.
What is car engine generator?
An alternator is a type of electric generator used in modern automobiles to charge the battery and to power the electrical system when its engine is running.
Can a car alternator power a house?
But if you’re living off the grid and doing so on a budget consider that you can run your house lighting system on a 12v circuit with battery backup simply by using automotive alternators and batteries (actually deep cycle marine batteries work better) with 12v lights.
And if the engine is running, you’ll find that using your car as a makeshift generator is typically going to be less efficient—and less effective—than just buying a real generator. If you have another heat source, like a wood-burning stove, you’re better off using that until the power comes back on.
What’s the difference between a alternator and generator?
An alternator is a device that converts mechanical energy into AC electrical energy.A generator is a mechanical device which converts mechanical energy to either AC or DC electrical energy. An alternator always induces an alternating current. A generator can generate either alternating or direct current.
