Ohm's Law states that the current (I) flowing in a circuit is directly proportional to the applied voltage (V) providing external factors, such as temperature, remain constant.
If current, then, is proportional to voltage, we can introduced a constant of proportionality which we call conductance. However, it is more usual to use the reciprocal of conductance: 1/R, where R is resistance.
So, Ohm's Law can be expressed as: I = V/R
For a circuit that obeys Ohm's Law, if we know any two of these quantities, then we can calculate the third. It's important to understand, however, that while the current and voltage are variables, resistance is a constant.

resistance = voltage/current

Using ohm's law what is the formula to find the resistance in a circuit?
Resistance of the circuit = (voltage across the circuit) divided by (current through the circuit)
State ohms law and give the formula?
The Ohm's law is defined as voltage propositional to current. The equation given by V=IR R IS THE PROPOSITIONAL CONSTANT
Where was georg Simon ohm born?
Ohm's most important discovery was in 1826 when he discovered the mathematical law of electric current called Ohm's law.
Formula for ohm when mohm is given?
mohm stands for milli ohms, each mohm is a 1/100 of an ohm.
What is the formula in getting the energy ohm's law?
The formula in getting the energy ohm's law is V = IR.
Why the ohms law not suitable for power formula?
Ohm's Law is unrelated to power.
Give the formula of state ohms law?
There is no equation for Ohm's Law. Ohm's Law simply tells us that, for ohmic or linear materials, the ratio of voltage to current is a constant.The equation you are, presumably, looking for is derived from the definition of the ohm, not from Ohm's Law, and that is resistance is voltage divided by current.
Using ohm's law what is the formula to find the resistance in a circuit?
Resistance of the circuit = (voltage across the circuit) divided by (current through the circuit)
What are the Limitations elements of ohm's law?
Ohms law does not consider inductance

Who discover the ohms law?
George Ohm, a German physicist.
What is the OHMS law formula for power?
There is no Ohm's Law formula for power. Ohm's Law simply states that the current flowing in a circuit is directly proportional to the applied voltage, providing external factors, such as temperature, remain constant. No mention of power, I'm afraid!
According to Ohm's Law what would the resistance be in a circuit with 40 volts and 8 amps?
5 Ohms Ohm's Law is V=I*R, 40V=8A*R, R=5 ohms.
Formula for ohm when mohm is given?
mohm stands for milli ohms, each mohm is a 1/100 of an ohm.
What is the formula in getting the energy ohm's law?
The formula in getting the energy ohm's law is V = IR.
What does I stand for in the Ohm's Law formula?
I is the current ( Amps) in the Ohm`s Law formula; V= I*R
