Voltage Current Amps

How to calculate with watts amps volts and ohms if you want to do an electrical calculation involving voltage current resistance or power reference the formulae circle below.

Voltage current amps. I a v v r ω. On the other hand high current with hundredth of ampere with ten twenty or thirty or more make nothing to human bodies like electric welding machine as the amount of voltage is not enough to push that level of. The current i in amps a is equal to the voltage v in volts v divided by the resistance r in ohms ω. Voltage is the cause and current is its effect.

In short high voltage with a few micro amperes cause nothing to the human body like in high voltage supplying cathode ray tube in traditional tv set or high static voltage in the comb. The current i in amps a is equal to the power p in watts w divided by the voltage v in volts v. Voltage is measured in volts current is measured in amps and resistance is measured in ohms. V or volts or voltage.

Voltage can exist without current. I a p w v v. The current i in amps is equal to the power p in watts divided by the voltage v in volts multiplied by the power factor pf multiplied by 3. 1 volt 1 joule coulomb.

Let s say for example that we have a circuit with the potential of 1 volt a current of 1 amp and resistance of 1 ohm. Amps vs volts. Amps to volts calculator volts to amps calculation. Current a power w voltage v for example find the amperage of a 100 watt light bulb at 120 volts.

Using ohm s law we can say. The voltage v in volts v is equal to the power p in watts w divided by the current i in amps a. Volts to amps calculation. The voltage v in volts v is equal to the square root of the power p in watts w times the resistance r in ohms ω.

Thus to find amps substitute the volts and watts in the formula. The voltage is equivalent to the water pressure. A neat analogy to help understand these terms is a system of plumbing pipes. Amperes amps and volts are the basic concepts that one learns when studying electricity in physics.

Current is the effect voltage being the cause. 1 ampere 1 coulomb second. I current in amps. V voltage in volts.

R resistance in ohms. The power p in watts w is equal to the voltage v in volts v times the current i in amps a. Current cannot flow without voltage. This is called ohm s law.

A or amps or amperage.
