Electric power is the rate at which work is done or energy is transformed into an electrical circuit. Electric power is measured in watts. Learn its definition, formula, unit along with solved examples at BYJU'S.
the resistance of high power devices is smaller than the low power ones. For example, the resistance of 100 watt (220 volt) bulb is smaller than that of a 60 watt (220 volt) bulb (see Figure). We have now three formulae for calculating electric power. These are : ...
Today at the flick of a switch or turn of a knob we are having instant power. This is possible due to theelectric current. It is one of the important discoveries that helped us to revolutionize our way of living. From the time we wake up till night, our life is fully dependent on e...

Forum:Introductory Physics Homework Help J Calculating Electric Field Strength Between Two Point Charges A +7.5 nC point charge and a -2.0 point charge are 3.0 cm apart. What is the electric field strength at the midpoint between the two charges? just give me the formula ?
Stay tuned with BYJU’S to learn more Physics concepts with the help of interactive video lessons. Visualising Electric Dipole Suppose there are two charges of equal magnitude “q”, separated by a distance, “d”. Let the first charge be negative and the second charge is positive. This com...
Modern physics gives a different meaning to the notion of action at a distance. The forces, which decrease with distance according to the inverse power laws (r-n) are considered to be forces that act at a distance. They include gravity and electromagnetic forces, which decrease proportionall...
