Electric current is the flow of electrons. In a better way, we can say that it is the flow of impulse.

One more important factor of electricity is resistance.

it opposes the flow of electric current.

According to OHM's LAW:

Voltade = Current * Resistance

The voltage across the conductor is directly proportional to the current through the conductor.

where "R" is the proportional constant.

Suppose, we don't oppose flow of high voltage current: let's take the example of MSEB, where large KOHMs resistors are being used. If they hadn't used them , then all electrical appliances would have been burnt.
