An amp is a standard measurement of electrical current - it's the current which flows when one volt is applied across a resistance of one ohm, and is given the symbol "I". Electrical power (in watts, but given the symbol "P") is given by multiplying voltage x current, or P=VI.
A car works on a 12volt system - the battery is 12v, so knowing that the headlamp bulbs and sidelight bulbs and everything else are 12volt, the lower power bits on a car (such as the 5watt sidelight bulbs) will take less current than the higher power bits (such as the 55watt headlamp bulbs - the 60watt main beams will take a bit more current). So in the fuse box you will find fuses with smaller current (amp) ratings for the lower-powered bits and higher amp ratings for higher powered bits. If the sidelights are all off one fuse, then the car is going to have at least four sidelight bulbs (4 x 5watts) and two number-plate illuminator bulbs of 5watts each, so 6 bulbs x 5watts gives a total load of 30w just for the sidelights. The current flowing through the fuse for this circuit would be I=P/V or 30 divided by 12 = 2.5amps. The fuse would perhaps be a 5amp or even a 10amp, so that it wouldn't just blow on the slightest pretext, like when a bulb blows.

What is a car amp for?
Depends on the amp. There are two different types. Theres one for your in car speakers and theres one for your sub. The small amps are to increase sound for the small speakers and the big amps are so you can have subwoofers and you can have lots of bass.
How many amps are a watt?
No.By which I mean: amps and watts are not just different units, they're different TYPES of units. You can't convert amps to watts without knowing the voltage (if you DO know the voltage, multiply volts by amps to get watts).
What are the different types of connectors used for connecting guitar amps to speaker wires?
The different types of connectors used for connecting guitar amps to speaker wires include 1/4-inch TS, Speakon, and XLR connectors.
Would you be able to use your car battery in a different car?
assuming it meets the CCA (cold crank amps) needed by the different car, then yes it can be used in another vehicle

How many amps are necessary for a car stereo?
A typical car stereo contains 4 amps. It is rare to find a car stereo without amps. Cars usually can contain up 8 amps, but you could always add more.
What are the different types of car insurance offered in California?
There are many different types of car insurance offered in California. You can get liability, collision, or full coverage.
Why do car amplifiers have low and high level inputs?
Different stereos has different output ranges. Thus amps have differing input ranges.
What are the different types of car radio antenna connector types available in the market?
The different types of car radio antenna connector types available in the market include DIN, ISO, Motorola, and SMB connectors.
How do car amps work?
Hi, Amps are electrical and the same in a car as elswhere. Amps are a quantity of electricity, voltage is the pressure pushing it and resistance is, as it sounds, how difficult it is to push it. Peace, crigby
