If a refrigerator is connected to a 120V outlet and draws 5A of current, what is the power consumption of the refrigerator?
600W
120W
5W
240W
Why is it important to plug values into the formula during the problem-solving process?
To verify the formula is correct
To calculate the desired variable
To skip unnecessary steps
To avoid converting units
What is the formula used to calculate the current (I) in the given problem?
I = P × R
I = √(P ÷ R)
I = P ÷ R
I = R ÷ P

It increases the flow
It decreases the flow
It remains the same
It becomes zero
What is electric current?
The resistance of a material to the flow of electricity
A measure of how much electric charge flows through a conductor in a given time
The potential difference across two points in a circuit
The capacity of a battery to store charge
Which kind of circuit has more than one path for electricity to flow?
