Ohms Law is used for the measurement of resistance. You can find the resistance in a series circuit using this equation; amps=volts/resistance or volts=amps x resistance.

The Power Law is used to find the wattage in the circuit. You can find the amount of watts using this equation: watts=volts x amps.

Comment

Ohm's Law has nothing whatsoever to do with either resistance or power.

The equation, R = E/I, is derived from the definition of the ohm, and not from Ohm's Law.

Ohm's Law simply describes a linear relationship between the potential difference across a conductor and the current through it. It does NOT describe the relationship between potential difference, current, and resistance.

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!


How do you find conductance using ohms law?

To find the conductance using ohms law,you take the inverse of the resistance(/R)


What are the materials that don't follow ohm's law called?

Everything follows ohms law. that's why it's called a law. There is no get out of jail free card when it comes to ohm's law. The full law even takes into effect radiative power, or power transferred through antennas.


Why in a circuit using power I equals Watts divided by Volts when you increase voltage the current will reduce so why does this differ from Ohms law when you increase voltage the current increases?

When you increase voltage (V) then, to get the same total power (W), the current (I) must be decreased. This result comes from the Power Law: Power = voltage x current Ohms Law does not deal with power at all, it deals only with the relationship between voltage, resistance and current: Voltage = resistance x current


Calculate the power loss when the voltage is 120 volts and has a resistance of 230 ohms?

By Ohm's law, 120 volts across 230 ohms is 0.522 amps. By the power law, that translates to 62.6 watts. You ask about power loss. In order to answer that, you need to provide more information, such as some change in configuration, or some other component. Please review and restate your question.
