You are watching: The continuous flow of electric charges through a material
1 Electric Current
2 Electric current is the constant flow of electric charges through a product. Needed to power any kind of electrical gadget. Measured in amp (A) Amps = amount of charge flowing past a provided point each second.
3 In order for electric current to exist, a circuit should first exist. An electric circuit is a complete, undamaged path through which electric charges can flow.
4 Series Circuit – circuit that has just one route for electric present to circulation. Below Parallel Circuit – A circuit that has more than one course for electrical present to circulation. Right photo
5 A conductor is a material via which charges have the right to flow easily. Electrons are loosely bound Conduction electrons develop an electrical existing Carry electrical charges An insulator is a product with which charges cannot circulation easily. Electrons are bound tightly to their atoms Soptimal the circulation of charges
8 Potential energy is capacity to execute work-related. Battery provides electric potential power Voltage is the difference in electric potential energy in between 2 locations. This deserve to additionally be referred to as potential distinction Voltage reasons a current in an electrical circuit Basically, it is the amount of pressure pushing an electric existing
9 A voltage resource is a machine that creates a potential distinction in an electric circuit.

The voltage in between the terminals is what reasons the charges to relocate Batteries Generators
10 Resistance is the meacertain of how difficult it is for charges to flow through a product. Greater the resistance, less the current Measured in ohm
11 Material Insulators have high resistance Conductors have low resistance Length Longer wire, even more resistance Shorter wire, much less resistance Diameter Wide wire, less resistance Thin wire, more resistance Temperature Higher temperature, resistance rises Lower temperature, lower resistance
