TOPIC 02 : CURRENT ELECTRICITY
Current electricity: Is the study of electric charges in motion
OR
Is a flow of electric charge
Electric current is a rate of flow of electric charges
Electric current (I)
- The common SI unit of current (I) is ampere (A)
- Ampere (A): Is the current through a point in a conductor when a charge of one coulomb passes through the point after every one second.
- The device used to measure electric current is called Ammeter.
- The other units are Mill Ampere (mA),Kilo ampere (kA), and micro ampere (ฮผA)
- Their equivalence to the ampere is as follows
