Basic Electricity┬а Electricity -┬а We cannot see it, but we can sense its effects like heating, chemical, magnetic etc. Electric Current -┬аThe flow of electrons is called current. The unit of current is Ampere and measured by ammeter. It is denoted by тАШIтАЩ. Voltage -Voltage can be defined as the difference of potential between two points of a circuit. One volt is the electric pressure which allows flow of one ampere of current against one ohm resistance. It is measured by voltmeter. Unit of voltage /potential difference is Volt. It is denoted by тАШVтАЩ. Direct current┬а- The current which does not change its direction and magnitude all the time is called direct
