Amps are a measure of current flow in an electrical circuit and represent the physical number of electrons passing a point in a circuit per second. 1 Amp of current flowing in a circuit means that every second 6.242 x 10e18 electrons goes past a point on the circuit.

Volts are a measure of how much energy each electron has with reference to another point. A voltage is a difference in energy and has no meaning without a reference point. 1 Volt means that for every 6.022 x 10e23 electrons, there is one joule of electrical energy.

Ohms are units of resistance, how much opposition the conductor provides to the current. Resistance is related to the phyiscal size of the conductor.

These three units relate to each other in Ohm's Law: Voltage = Current x Resistance because if there is more opposition to the current, there needs to be more energy to make it flow.

A common illustraiton of an electrical circuit is a water pipe: Amps is how fast the water is flowing, Voltage between two points is the pressure difference and Ohms describe how big the pipe is and if there is any obstruction inside it.

If voltage is 12 volts and ohms is 0.5 how many amps in circuit?

Ohm's law: Volts = Amps * Ohms, or Amps = Volts / Ohms 12 volts / 0.5 ohms = 24 amps


Formula for ohms law?

ohms=amps/volts Amps= volts/ohms Volts = Amps*Ohms


How do you find OHM?

Ohms can be found by using these formulas. Ohms = Volts/Amps, Ohms = (Volts (squared))/Watts, Ohms = Watts/(Amps (squared)).


How do you work out the current?

There are three formulas that you can use. Amps = Volts/Ohms Amps = Watts/Volts Amps = sq root of Watts/Ohms


How many amps are in ohms?

It's not that simple. The basic formula is Volts / Ohms = Amps. For 30 Volts you'd get 0.5 Amps, for 60 Volts you'd get 1 Amp, for 120 Volts you'd get 2 Amps.


If volts change then amps and ohms stay the same?

The ohms will usually stay the same unless the Amps are somehow effecting the temperature. The Amps will always change with the volts.


10 ohms plus 9 volts equals how many amps?

Ohm's Law: Voltage = Amperes times Resistance 9 volts = amps * 10 ohms amps = .9


.01 amps equal how many volts?

To calculate volts, you also need to know the resistance (ohms) in the circuit according to Ohm's Law. The formula to find volts is V = I x R, where V is voltage, I is current in amps, and R is resistance in ohms. So, to determine volts given 0.01 amps, you'd need the resistance value.


A 240 volt single phase circuit has a resistive load of 8500 what is the net calculated current to supply this load?

Ohm's law: Volts = Amps * Ohms, or Amps = Volts / Ohms 240 volts / 8500 ohms = 28 milliamps


What effect are there when resistance is increased in the size of the current?

Current is inversely proportional to resistance. If you double the resistance, you halve the current. Ohm's Law: Volts = Amps * Ohms Solve for Amps: Amps = Volts / Ohms


If the potential difference across a load is 60 volts and the resistance of the load is 10 ohms the current is amperes.?

It's not that simple. The basic formula is Volts / Ohms = Amps. For 30 Volts you'd get 0.5 Amps, for 60 Volts you'd get 1 Amp, for 120 Volts you'd get 2 Amps.


What is a difference between vollage and watt?

Watts = Volts / Ohms Watts = Volts x Amps
