Electric Current
Electric Current (pronunciation: /ɪˈlɛktrɪk ˈkʌrənt/) is a fundamental concept in the field of Electrical Engineering and Physics.
Etymology
The term "Electric Current" originates from the Latin words 'electricus' meaning 'like amber' and 'currere' meaning 'to run'.
Definition
Electric Current refers to the flow of Electric Charge through a Conductive Material such as a wire. It is measured in Ampere (A), a unit named after the French physicist André-Marie Ampère.
Related Terms
- Voltage: The electric potential difference between two points. It is the force that pushes the current through a circuit.
- Resistance: The opposition to the flow of electric current, resulting in the conversion of electrical energy into heat.
- Ohm's Law: A fundamental principle in electricity which states that the current passing through a conductor is directly proportional to the voltage across it, and inversely proportional to its resistance.
- Direct Current (DC): A type of electric current that flows in one direction.
- Alternating Current (AC): A type of electric current where the flow of electric charge periodically reverses direction.
