What mathematical equation is used for a circuit to find I when you know P and R?

I= { P/ R}- square root

The ? is the amount or unit of energy used to measure the amount of heat or work produced or consumed in a system.

Joule

The ? in the circuit uses power to change electrical energy into some other form of energy.

Load

Prove that the amount of power consumed by a load is directly related to the amount of voltage applied to the load and the amount of current flowing through the load with a mathematical equation.

P= E x I

? in a circuit is the amount of work being done per unit of time.

Power

The amount of power consumed by a load is directly related to the amount of voltage applied to the load and the amount of current flowing through the load.

True

The total amount of heat produced in a conductor is directly proportional to the resistance times the square of the current. Select one:

True

The unit of measurement of electrical power is the ? .

Watt

Power is what is consumed when a(n) ? is applied to a circuit and current flows through the load.
