DONE BY SHAYAAN BIN UMAR

2. Electricity is the set of physical phenomena associated with the
presence and motion of matter that has a property of electric charge.
Electricity is related to magnetism, both being part of the phenomenon
of electromagnetism

3. ELECTRIC charges are made up of positive chargers (protons) and
negative charges (electrons)
.when these charges flow in a circuit, a current is produced.

4. How does electricity flows .
The battery in a circuit gives energy to the electrons and pushes them around a circuit,
from the negative terminal of the cell, round the circuit and back to the positive
terminal of the cell.

5. How to measure current.
.The SI unit for electric current is ampere (A).
.smaller current are measured in Milliamperes (Ma).

6. Instrument to measure current
. An ammeter is an instrument used for measuring current.

7. Ammeter
.It must be connected in series in the circuit.
