WebName of the SI unit of current is Ampere. Ampere can be defined as the one unit of charge flown through a given circuit in one second. 1 A m p e r e ( A ) = 1 S e c o n d ( s ) 1 C o u l o m b ( C ) WebElectric power is the rate of doing work or it is the work done in 1 second. The S. I. unit of power is ‘Watt’. If a current of 1 ampere flows through a metallic conductor at a potential difference of 1 volt, the power is said to be 1 watt.

WebUnit of Current. Since the charge is measured in coulombs and time in seconds, so the unit of electric current is coulomb/Sec (C/s) or amperes (A).The amperes is the SI unit of the conductor. The I is the symbolic representation of the current.. Thus, a wire is said to carry a current of one ampere when charge flows through it at the rate of one coulomb per … WebIt is defined as, An electric potential is the amount of work needed to move a unit positive charge from a reference point to a specific point inside the field without producing any acceleration. Its SI unit is j / c = V o l t s
WebElectric Current: Electric current has both the magnitude and direction but it does not follow the vector law of addition, therefore, the electric current is a scalar quantity. It is simply defined as the rate of flow of electric charges through a conducting medium. It can be expressed in C/s C / s or A A (SI unit).
