Let's explore what is Electric current
Definition
Electric current is the flow of electric charge. In most cases, it involves the movement of electrons through a conductor, such as a wire. The unit of electric current is the ampere (A). Current can be either direct current (DC), where the electrons flow in one direction, or alternating current (AC), where the flow of electrons periodically reverses direction. Electric current plays a fundamental role in various electrical devices and systems, including circuits, power distribution, and electronic devices. It is a key concept in the study of electricity and is governed by Ohm's Law, which relates current, voltage, and resistance in a circuit.
The Flow of Charge:
Imagine a closed loop path made of conducting material, like a wire. This is your circuit.
Electric potential, like a voltage source (battery), creates a push, encouraging electrons to flow through the circuit.
Electrons, the charge carriers, act like little cars whizzing along this highway, carrying electric charge with them.
The rate at which these charged particles flow is the electric current, measured in amperes (A). One amp is equal to one coulomb of charge flowing past a point in one second.
Key Players in the Circuit:
Ohm's Law:
What is the unit of electric current?
How do you calculate the equivalent resistance of resisitors connected in series?
What is the difference between AC and DC current?
How do you measure the current in a circuit using an ammeter?
What is the effect of increasing the voltage across a circuit on the current?
How do you calculate the equivalent resistance of resistors connected in parellel?
How do you measure the voltage across a circuit element using a voltmeter?
What is the effect of adding more batteries in series on the current in a circuit?
