Current Amp Voltage Formula

Ohm s law can be rewritten in three ways for calculating current resistance and voltage.

Current amp voltage formula. Sometimes you will see this formula written as w a x v. 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. Amp watt volt. Now we can see that if we know two of the values for ohm s law we can solve for the third.

The voltage v in volts v is equal to the current i in amps a times the resistance r in ohms ω. The current flowing through this resistor produces the voltage output of the amplifier. Power formula 1 electrical power equation. For example a current of 2a flowing through a bulb with a voltage of 12v across it generates 24w of power.

The above ohm s law calculator is reliable to do so. If a current i should flow through a resistor r the voltage v can be calculated. When current and resistance are known you can easily find out the voltage using a simple voltage formula. I a p w v v so amps are equal to watts divided by volts.

Voltage measures the force or pressure of the electricity. A w v. As a result the voltage drop v f is compensated and the circuit behaves very nearly as an ideal super diode with v f 0 v. Dc watts to amps calculation formula.

The mathematical formulas of ohm s law. If there is a voltage v across a resistor r a current i flows through it. The common emitter amplifier circuit has a resistor in its collector circuit. The value of this resistor is chosen so that at the amplifiers quiescent operating point q point this output voltage lies half way along the transistors load line.

V i r. The current i in amps a is equal to the power p in watts w divided by the voltage v in volts v. The voltage v in volts v is equal to the power p in watts w divided by the current i in amps a. The number of watts is equal to amps multiplied by volts.

What is the current in amps when the power consumption is 330 watts and the voltage supply is. Find the voltage applied across 15 kω resistors when 10 ma current flows. First version of the voltage formula. So the current is lower in the tank with higher resistance.

If there is ac look also at the power factor pf cos φ and φ power factor angle phase angle between voltage and amperage. For example if the current is 3 amps 3a and the voltage is 110v you multiply 3 by 110 to get 330w watts. 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. The op amp compares the output voltage across the load with the input voltage and increases its own output voltage with the value of v f.

Voltage v current i x resistance r v volts i amps x r ω for example.
