A charge of #40 C# passes through a circuit every #8 s#. If the circuit can generate #16 W# of power, what is the circuit's resistance?
One of the formulas for electric power is
Also, electric current is defined as the flow of charge.
Mathematically, this is expressed as
Let's substitute this expression of
Then, let's rearrange the equation to express it in terms of
Now, let's substitute the values for electric charge, time and electric power:
