Study Notes
Electric Circuits
- The flow of electric charge through a closed path is known as an electric current.
- The unit of electrical potential difference or voltage is the Volt (V).
- The property of a material that opposes the flow of electric current is electrical resistance.
- The SI unit of electrical resistance is the Ohm (Ω).
- The basic unit of electrical charge is the Coulomb (C).
- A circuit breaker is a device that interrupts the flow of electric current in an electrical circuit when it exceeds a certain level, protecting the circuit from damage or fire.
