Ohm's Law relates voltage (V), current (I), and resistance (R) in an electrical circuit, expressed as V = IR. Power (P) in an electrical circuit can be calculated using the formula P = VI, which can be further expressed in terms of resistance as P = I²R or P = V²/R. This shows that power is directly proportional to the square of the current or voltage, while also being influenced by resistance. Therefore, Ohm's Law provides a foundational understanding of how voltage, current, and resistance interact to determine electrical power.
What else can I help you with?
What law would you use to determine the voltage of a power supply?
ohms
What is difference between resistance and reactance while both are measured in ohms?
Resistance is constant no matter the frequency applied. Reactance varies depending on the frequency of the power applied to it.
What are typical values of input impedance and outoput impedance of ce amplifiers?
Output of the power amplifier is smaller 0.1 ohms and input of the loudspeaker is more than 4 ohms.
What is the amount of power loss on a transmission line that is transmitting 10 MW at 500 kV with 1000 ohms?
Line current = 10MW / 500kV = 20A Assuming the 1000 ohms is the resistance of the entire transmission line, end to end. Power loss = line current ^ 2 * line resistance = 20A ^ 2 * 1000 ohms = 400 KW
What is the power dissipated by a parallel resistor of 100 ohms with a 40v power source?
You may find it helpful to use Ohm's law and the definition of electrical power.
How powerful are ohms?
Ohms do not relate to power per se. Ohms do however contribute how much power a circuit can deliver. In a given circuit the lower the resistance (measured in ohms) the higher the current & higher the power. This is assuming the voltage remains constant.
What is the power if current is 1.17A and resistance 1.1k Ohms and Round result to whole number?
Power = 1 A and resistance = 1100 Ohms.
Difference between account payable and bills payable?
Accounts Payable releted to Creditors and Bills payable releted to bank.
Why the ohms law not suitable for power formula?
Ohm's Law is unrelated to power.
What are watts amps and ohms?
ohms is a measure of resistance(R) in a circuit. Watts is a measure of the power(P), in this case lets assume it is the power used by the resistive element (lamp, heater etc). Power(watts)=Current(Amps)x Current(amps) x Resistance(ohms) or Resistance (ohms)=Power(W)/(current x current)
How many ohms in 800 watts?
To calculate the resistance in ohms, you also need to know the voltage. The formula to find the resistance in ohms is R = V^2 / P, where R is the resistance in ohms, V is the voltage, and P is the power in watts.

What is ohms law formula used for?
It is used in Science: Energy and Power.
