Question
What is the power of a circuit with a current of 
and a resistance of 
?
What is the power of a circuit with a current of
Answer
The standard equation for power is:
We are given only current and reistance, meaning we must manipulate this equation so that only those variables are present. To do this, we can substitute Ohm's law for voltage.
Now we have an equation for power that uses only current and resistance. Plug in the values given in the question to find the final answer.
