Volts Divided By Ohms

Introducing the constant of proportionality the resistance one arrives at the usual mathematical equation that describes this relationship.

Volts divided by ohms. Resistance calculation from. The kiloohm is a multiple of the ohm which is the si derived unit for electrical resistance. Resistance voltage current. One kiloohm is equal to 1 000 ohms which is the resistance between two points of a conductor with one ampere of current at one volt.

The resistance r in ohms ω is equal to the voltage v in volts v divided by the current i in amps a. R v 2 p. The voltage is equivalent to the water pressure the current is equivalent to the flow rate and the resistance is like the pipe size. This is true for many materials over a wide range of voltages and currents and the resistance and conductance of electronic components made from these materials remains constant.

Enter the power in watts w resistance in ohms ω then press the calculate button to get the result in amps a. P e 2 r p i 2 r p e i. The resistance r in ohms ω is equal to the squared voltage v in volts v divided by the power p in watts w. Ohms to amps calculation with watts.

The power p in watts w is equal to the voltage v in volts v times the current i in amps a. In the metric system kilo is the prefix for 10 3 kiloohms can be abbreviated as kω. I e r i p e i sqrt p r r e i r e. R v i.

Ohm s law states that the current through a conductor between two points is directly proportional to the voltage. The bavarian physicist georg simon ohm derived a formula in which the resistor current i in amps a is equal to the resistor s voltage v in volts divided by the resistance r in ohms ω. Ohm s law defines the relationship between power voltage current and resistance. It says that the current is equal to the voltage divided by the resistance or i v r.

The current i in amps a is equal to the voltage v in volts v divided by the resistance r in ohms ω. Ohms volts amps. Resistance calculation from voltage and power. For example 1 kiloohm can be written as 1 kω.

The various possible formulas for ohm s law are as follows. Resistance voltage 2 power. Ohm s law states that the current through a conductor between two points is directly proportional to the voltage across the two points. This is known as ohm s law.

V v i a r ω. E sqrt p r e p i e i r. Resistance r in ohms is equal to the square of the voltage v in volts divided by power p in watts hence the formula will be. Where p power in watts e voltage in volts i current in amps r resistance in ohms.

Where i is the current through the conductor in units of amperes v is the voltage measured across the conductor in. Resistance volts watts. The resistance r in ohms ω is equal to the power p in watts w divided by the squared current i in.
