ELECTRICITY IS THE FLOW OF ELECTRONS .. 

HENCE IT CARRY NEGATI VE CHARGE. THE CONVENTIONAL DIRECTION OF CURRENT IS POSITIVE TO NEGATIVE BUT THE ELECTRONS MOVE NEGATIVE TO POSITIVE.ELECTRIC CURRENT[I] IS PRODUCE WHEN POTENTIAL DIFFERENCE IS CREATE BETWEEN TWO ENDS OF CIRCUIT WHICH CONNECTTED TO BATTERY. AND ACCCORDING TO 10 STANDARD IT'S VERY LARGE TO EXPLAIN.

Electricity means its the flow of elctrons from a higher potential to a lowerpotential.for the flow of current asource is in need,ie a cell or abattery.suppose a cu wire is connected between+ve terminal of a battery then to a switch and to bulb and finally to the -ve end of the battery.If the switch is ON,the bulb will glow.switch is used to control  the flow of electrons.the conventional flow of electrons is from-ve to +ve but external flow of current is from +ve to -ve terminal.current is measured in amperes.ammeter isused to measure the current.voltmeter is used to measure the p.d between the ends of a conductor.its unit is volt
