Question

1)What is electric current?
2)What Makes lighting flash?
3)What is resistance?

Answer 1

Answer:

1. An electric current is the rate of flow of electric charge past a point or region. An electric current is said to exist when there is a net flow of electric charge through a region. Electric charge is carried by charged particles, so an electric current is a flow of charged particles.

2. Lightning is an electrical discharge caused by imbalances between storm clouds and the ground, or within the clouds themselves

Answer 2

Answer:

1) An electric current is the rate of flow of electric charge past a point or region. An electric current is said to exist when there is a net flow of electric charge through a region. Electric charge is carried by charged particles, so an electric current is a flow of charged particles.

2)Lightning is an electrical discharge caused by imbalances between storm clouds and the ground, or within the clouds themselves. ... This heat causes surrounding air to rapidly expand and vibrate, which creates the pealing thunder we hear a short time after seeing a lightning flash.

3)Resistance is a measure of the opposition to current flow in an electrical circuit.
