Volts Amps Resistance Formula

V 10 ma x 15 kω.

Volts amps resistance formula. For example if you have a server with a voltage of 12v dc and an amperage of 0 55amp to know the resistance you must divide 12 between 0 55 the result will be. The voltage v in volts v is equal to the current i in amps a times the resistance r in ohms ω. This is known as ohm s law. The resistance r in ohms ω is equal to the voltage v in volts v divided by the current i in amps a.

The voltage is equivalent to the water pressure the current is equivalent to the flow rate and the resistance is like the pipe size. There is a basic equation in electrical engineering that states how the three terms relate. If you want to do an electrical calculation involving voltage current resistance or power reference the formulae circle below. This formulae circle is very useful for many electrical engineering.

How to calculate with watts amps volts and ohms. If we increase the resistance the current will reduce. Ohm s law calculator calculation calculate ohms power formulas mathematical ohm s law pie chart electric voltage drop electric current resistance formula watt s law emf magic triangle tip online voltage volts resistor resistance amps amperes audio engineering e v i r p v i calc conductivity resistivity relation relationship eberhard sengpiel sengpielaudio. 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.

So the current is lower in the tank with higher resistance. It says that the current is equal to the voltage divided by the resistance or i v r. How to convert from amps to resistance in 1 step only. If we increase the voltage the current will increase.

Current a voltage v resistance ω for example let s find the current of a 12 volt circuit with 10 ohms of resistance. Voltage volts current amps x resistance ω. The voltage v in volts v is equal to the power p in watts w divided by the current i in amps a. V 150 v.

How to calculate power. Now we can see that if we know two of the values for ohm s law we can solve for the third. Find the voltage applied across 15 kω resistors when 10 ma current flows through it. The simplest way to convert from amps to resistance is by the formula of ohm s law dividing the voltage between the current.

Because the resistance is greater and the voltage is the same this gives us a current value of 0 5 amps. Since the current is set by the values of the voltage and resistance the ohm s law formula can show that. To convert from volts to resistance only the voltage between the current must be divided with the formula of the law of ohm. For example we can calculate the power in watts by referencing the yellow area in the circle.

For example if you have an electronic processor with a voltage of 5v dc and an amperage of 0 2 amp you must divide 5 by 0 2 as follows 5 0 2 25 ohm. To calculate amps divide the voltage by the resistance in ohms.
