To find power in a power equation, use the formula ( P = IV ), where ( P ) represents power in watts, ( I ) is the current in amperes, and ( V ) is the voltage in volts. If you have resistance instead, you can use ( P = I^2R ) or ( P = \frac{V^2}{R} ) depending on the known variables. Simply plug in the known values into the appropriate formula to calculate the power.

What are Ohms Law and the Power Law?

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.CommentOhm'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 equation to calculate power when circuit current and resistance are known what is the equation?

The power ( P ) in an electrical circuit can be calculated using Ohm's Law, which relates voltage ( V ), current ( I ), and resistance ( R ). The equation is given by ( P = I^2 R ), where ( P ) is the power in watts, ( I ) is the current in amperes, and ( R ) is the resistance in ohms. This formula shows that power is directly proportional to the square of the current multiplied by the resistance.

What mathematical equation is used for a circuit to find I when you know P and R?

To find the current (I) in a circuit when you know the power (P) and resistance (R), you can use the equation derived from Ohm's Law and the power formula: ( P = I^2 R ). Rearranging this gives ( I = \sqrt{\frac{P}{R}} ). This equation allows you to calculate the current based on the known power and resistance values.


How do you find out if a problem is linear or exponential?

You find out if a problem is linear or exponential by looking at the degree or the highest power; if the degree or the highest power is 1 or 0, the equation is linear. But if the degree is higher than 1 or lower than 0, the equation is exponential.
