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
