Do cars use electricity?

Answer 1

Yes,

The dashboard uses electricity to operate, including the radio.
The battery also is needed to turn the starter motor.
The internal combustion engine requires electricity to operate.

The spark plug fires a spark into the piston chamber and that creates an explosion of the gas fumes which pushes the piston, so cars can't operate without electricity.

Answer 2

Well, they produce it, just as a generator does. The alternator is composed of a rotor, and a stator. In this case the stator would be a bunch of wound up wire, and the rotor is mechanically driven by the drive belt. The rotation of the rotor draws the electrical energy from the wire. The end result is mechanical energy converted into electrical, allowing you to recharge your battery, and power your electrical loads. Of course theres more to it, but it works a lot like an electric motor. Also, the alternator produces AC power, but than converts it to DC. I'm not sure why this is so, but I know this is the case. Early DC car generators were called "dynamos".

Answer 3

Cars use electricity generated by the petrol motor (after the car is started). It is not the same electricity as in homes, as it is DC (Direct Current). As mentioned it powers the lights, dash, coil (for spark plugs) and so on. Belt driven alternator converts the mechanical energy from the engine - into 12 Volt DC electrical energy used by the car.

Answer 4

The trend is to serve all energy requirements on-board by electricity. Hydraulic or belt-driven systems make way for a copper wire and electric motor. Only the propulsion system is not electric, but this is changing rapidly as well.

The same trend is taking place in airplanes - the 'all-electric airplane' is of course jet driven, but everything else is electric.

The cost of on-board electricity is expensive. As a rough guide, there is about 9 kWh of energy in a liter of fuel, and with combustion engines being 20% efficient at best, the cost of a kWh of on-board electricity is at least half a liter of fuel.

This explains sizeable fuel savings when switching off airconditioning, or when replacing hydraulic steering by 'drive by wire'.

Answer 5

A simple question for you. How does the headlamps glow? Its not candles, right?

Of course, the cars use electricity. From the lights to the sparkplugs, the car is dead without its electricals.

Answer 6

some electric cars does, but not very efficient or fast.
On many university campus, you'll see the buildings and grounds staff driving around a small open top car slowly. Those are electric cars

Answer 7

Well, they have a battery and an alternator to keep it charged so, I'd say that they obviously must use electricity...Lights, Indicators, Spark Plugs, Starter motor, CD/Radio, Central Locking, Dashboard, Cigarette lighter ...etc.

Answer 8

Yes they have an electrical system.

Answer 9

yes

Answer 10

No. It has a battery just to keep the front tires on the road.
