Question

definition of the following..
1. dynamic electricity

2. current( it's direction of flow)( positive negative and also north or south!.??.)

3. charge (it's direction of flow)

4. Subatomic particles in electricity

5. in electrical appliances does both electrons and protons move or only electrons move.

6. define - flow of electric charge through conductors in one direction.

Answer 1

1. Dynamic electricity is same as current. it is the flow of electric charges through a conductor.

2. Electric current is the flow of electric charge.

charge can be positive or negative.

direction of current:
- in the same direction as the flow of positive charge
- in the opposite direction of the flow of negative charge

there is no north or south.

3.Charge: the property of matter where it has more or fewer electrons than protons in its atoms.
Matter is positively charged if it contains more protons than electrons, and negatively charged if it contains more electrons than protons.

4. Subatomic particles contributing to electricity:
electron - gives negative charge
proton- gives positive charge

5. in electrical appliances like tv, mobile, etc, where current flows through wire,

only electrons move.

6. The electrons move in one direction, opposite to the direction of current.

the current flows from the positive terminal of battery(which gives voltage) to its negative terminal.
electron floes from the negative terminal to the positive terminal.
