ELECTRICITY AND MAGNETISM​

Electric Current​

Is the movement of charged particles in a specific direction.

Frech physicist Andre Marie Ampere

​ELECTRONS- current carriers

Voltage​

Is also known as EMF (electromotive force ) or potential difference (pd).

Electric pressure that causes current to flow. ​

​Resistance

​The opposition a material offers to current.

​FACTORS THAT AFFECTS RESISTANCE

​

SIMPLE ELECTRIC CIRCUIT​

​IS CONDUCTING LOOP IN WHICH CURRENT CAN TRANSFER ELECTRICAL ENERGY FROM SUITABLE SOURCE TO A USEFUL LOAD.

​2 TYPE OF CIRCUITS

​

​Series Circuit- Current flow through a single path without branching

​Current flows through more than one path

​ELECTRICAL POWER IN A CIRCUIT

​ENERGY CONSUMPTION
