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
