Answer / Solution**Some Other Current Units**

Answer / Solution

Basically, * A closed and contineous path of an electrical current is called an electric circuit*. Normaly an electric circuit consists of some electric power source, switches, wire or cables and electric devices like bulbs, resistors tubelight etc.

The SI unit of electric current is ampere denoted by character "A". Or we can say that ** Ampere is one of the SI base units for electric current**. It measures the

1 Ampire = 1Coulamb / 1 second

Since the charge is measured in coulombs and time in seconds, so the unit is **coulomb/Sec** (C/s) or **amp**. Meanwhile, the formula for electric current is given as follows:

I = V/R

Where*, ***I = Electric Current, V = Voltage **
