The thing that determines whether you get an electric shock is the voltage. whether the source is AC or DC is not determinant. Car batteries are usually 12v, which is not sufficient to drive a current through your skin. The voltage of Mains electricity at 110 or 220 volts on the other hand is easily high enough to give you a jolt. The fact that AC voltages are conventionally stated as RMS (a kind of average) means that the actual peak voltage will be higher still.
Telephone lines carry around 90v DC when a call is incoming, which can also give you a shock.
I have heard that DC is more dangerous than AC because DC tends to cause your muscles to contract, so that you grip the source, whereas AC tends to throw you off. I'm happy to say that I don't have first hand experience to confirm this!
The apmeres depend on the resistance of the circuit. The battery will be a certain voltage, and dividing the voltage by the resistance gives you amperes. V = I*R
the alternator voltage at the battery should be between 12.4voltsv-13.6 volts
the voltage regulater is built into the alternator it regulates how much volts gives to the battery
Online forums believe that it gives you twice the battery life.Some sources claim it's even more.
Usually not, but it may. The number of cells depends on the cell voltage, and to get a 12V, 4-cell battery you'd need to use a chemistry that gives a 3V cell voltage - which some Lithium-type primary cells do.
vinegar makes a battery because of the ions in the vinegar which was reacting to the metal which gives of a electric circuit
Two wires are needed so that the electric current has a circuit to flow round. For a simple circuit, the voltage between the wires, multiplied by the current in amps, gives the power in watts, which is how fast energy is used up (joules per second). Also, the voltage divided by the current gives the resistance of the load, in Ohms.
your laptop shocks you because your battery is full and when you are charging it has to get rid of the extra energy so you get shocked.
The hardware in a computer need electric to run, this gives it the power that all the hardware needs and each connector has a certain voltage.
The device that uses chemical energy to give charges electric potential energy is a battery because it uses chemical energy which gives off potential electric charges.
a tube that gives of electric
Electrical power in the form of a flow of current across a voltage difference is converted into heat energy by vibrating the electrons and atoms of the filament. Due to the heat, it gives out orange-red light. Thus it can be said that an electric toaster gives out heat energy as well as light energy.
