There are many different formulae for finding power in different situations.
The primary definition of power can be shown by the formula, "P = E/t", as power is the amount of energy which changes form per unit time.
If you are using electric circuits, "P = (I^2)*R" and "P = (V^2)/R" can also be used, where P is the power dissipated by a resistor with resistance 'R', and a voltage 'V' across it and current 'I' through it.

What is the current in a circuit that has a resistance of 30 ohms and a power of 2 watts?
To find the current in the circuit, you can use the formula: Power = Current^2 * Resistance. Given the values, you can rearrange the formula to solve for current: Current = sqrt(Power / Resistance). Plugging in the values, you get Current = sqrt(2 / 30) which simplifies to approximately 0.27 amperes.
How do you find power in a power equation?
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.
