Why does AC voltage gives a electric shock and DC sources like car battery do not?
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!

How many amps is a lawn mower battery?
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
How much voltage the alternator of Skoda octavia gives?
the alternator voltage at the battery should be between 12.4voltsv-13.6 volts
Your alternator is on top of the motor and what does the voltage regulator do also where is it on a 99 Concorde?
the voltage regulater is built into the alternator it regulates how much volts gives to the battery
How does the energy that the battery gives to each coulomb of charge compare to the energy that this charge gives to the load?
The energy that a battery gives to each coulomb of charge is equal to the voltage of the battery, measured in volts. This energy is used to move the charge through a circuit. The energy that this charge gives to the load is determined by the resistance of the load and the current flowing through it, according to Ohm's Law (E=IR). The relationship between the battery's voltage and the load's resistance and current ultimately determines the efficiency of energy transfer in the circuit.
Can 5v charger charge a 7.5v battery?
yes it just takes longer to charge, but check how much Amps (A) your charger gives out and how much Amps your battery can take if the battery has lower Amperage (A), don't do it, otherwise you're fine. <<>> No, the charging unit has to have a higher output that the battery voltage that it is charging. For example, on a 12 volt car battery the charging rate is 13.5 volts.
How much longer will the 1200mAh battery last compared to the stock battery for Sony PSP?
Online forums believe that it gives you twice the battery life.Some sources claim it's even more.
Does a 12 volt battery contain four cells?
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.
What is the voltage at the location of a 0.0001-Coulomb charge that has an electric potential energy of 0.5 joules?
Electric Potential = Electrical Potential Energy/ Charge The measurement for electric potential is call the volt. Electrical Potential is often called voltage. Voltage or Electrical Potential = 0.5 Joules / .0001 Coloumb = 5000
Why does vinegar make a battery?
vinegar makes a battery because of the ions in the vinegar which was reacting to the metal which gives of a electric circuit
Why an electric connection has 2 wires?
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 gives you electric shock why?
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 purpose of the power supply in a PC is to?
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.
