Because power is a function of voltage multiplied by current and both voltage and current doubled from their previous values the power will increase by a factor of 2 x 2 or 4.

I P R Corresponding units. Ampere A Watt W Ohm Ω Where P is the electric power. You can check this by dividing 432 watts by 108 watts and seeing that the ratio between them is indeed 4.

Download the Pdf of class 12 formula booklet physics of chapter Current Electricity from the link given below. If a charge Q flows through the cross-section of a conductor in time t the current I then IQt. Electric Current Formula and Unit The conventional direction of electric current is taken as opposed to the direction of flow of electrons.

These physics formula sheet for chapter Current Electricity is useful for your CBSE ICSE board exam as well as for entrance exam like JEE NEET. Later Ohm studied the relation between current and potential difference. The rate of flow of charge through a cross section of some region of a metallic wire or an.

The equation for the total resistance in a parallel circuit is. 4 Compute for the total current. Therefore the current is equal to charge q by time t.

622 The moving particles are called charge carriers which may be one of several types of particles depending on the conductor. Current electricity is basically the movement of free electrons in the conductor per unit time. Drift Velocity where is relaxation time E is Electric Field Current in terms of drift velocity where n is free e- density.
