The Big Power Formulas Electrical and mechanical power calculation strength Power Formula 1 Electrical power equation. Definition of Power in Physics. The current formula is given by.
It is represented as P. I 31428 A. T V.
Position of any object. Mechanical Energy Kinetic Energy Potential Energy. Electric power is defined as the rate at which electrical energy is transferred by an electric circuit.
P V x I. Also includes the value of Physical constants. I2 V2 R where power P is in watts voltage V is in volts and current I is in amperes DC.
The Energy expended to do work in unit time is termed as Power. This is expressed most simply as PE qV where q is the charge moved and V is the voltage or more precisely the potential difference the charge moves through. Ampere A volt V ohm Ω This formula is derived from Ohms law.
Time taken t 4 hours. Power is the rate at which energy is moved and so electric power is. An electrical lamp lights for 4 hours and draws a current of 05 A.
21032019 Power formula can be rewritten using Ohms law as P I2R or P V2R. Voltage current x resistance. Power P I.
V R. Power voltage x current. Charge current x time.
This pdf sheet of chapter Electricity is useful for last minutes revision before exam. Thus the formula for electric energy is given by. The electric current is given by.
