# If a current of #8 A# passing through a circuit generates #14 W# of power, what is the resistance of the circuit?

##### 1 Answer

The resistance in the circuit will be 0.22

#### Explanation:

I would combine two laws I have memorised here: **Ohm's Law**,

#V = IR#

and the **Power Law**

#P = VI#

I have a current,

So I want a formula that includes only those three things. If I want to get rid of the

#P = (IR) * I = I^2 * R#

I need to rearrange to make

#R = P/(I^2) = 14/(8^2) = 14/64 = 0.22 color(white)(a)Omega# (rounded to two decimal places).
