Electric current
Electric current refers to the flow of electric charge in a conductor. It is the rate at which electric charges, typically electrons, move through a specific point in a circuit. Electric current is measured in units of amperes (A).
There are two types of electric current:
- Direct Current (DC): In a direct current, the flow of electric charge is in one direction only. The magnitude and direction of the current remain constant over time. Batteries and cells are examples of sources that provide direct current.
- Alternating Current (AC): In an alternating current, the flow of electric charge changes direction periodically. The magnitude and direction of the current vary sinusoidally with time. AC is commonly used in electrical power transmission and distribution systems.
The flow of electric current is driven by a potential difference, or voltage, across a conductor. It is influenced by the resistance of the conductor, which opposes the flow of current. According to Ohm’s Law, the current (I) in a conductor is directly proportional to the voltage (V) and inversely proportional to the resistance (R), expressed as I = V/R.
Electric current plays a fundamental role in various electrical and electronic devices. It powers appliances, lighting, and electronic gadgets. Understanding electric current is crucial in fields such as electrical engineering, physics, and electronics.
