Electric current and circuits- Electric current is the flow of electric charge through a conductor. It is caused by the movement of electrons within the conductor. The unit of electric current is the ampere (A).
In a closed loop, called an electric circuit, current can flow continuously when there is a complete path for the electrons to travel. A circuit typically consists of several components, including a power source (such as a battery or generator), conductive wires, and various devices or loads (such as light bulbs, motors, or resistors) that utilize the electrical energy.
Current flows from the positive terminal of the power source, through the circuit components, and returns to the negative terminal of the power source. This flow is due to the potential difference or voltage provided by the power source, which causes the electrons to move.
Ohm’s Law, named after the German physicist Georg Simon Ohm, relates the current (I), voltage (V), and resistance (R) in a circuit. According to Ohm’s Law, the current flowing through a conductor is directly proportional to the voltage across it and inversely proportional to its resistance. The formula for Ohm’s Law is:
I = V / R
where I is the current in amperes, V is the voltage in volts, and R is the resistance in ohms.
In addition to resistors, circuits may also contain other components such as capacitors, inductors, diodes, and transistors, which introduce specific behaviors and functions to the circuit.
It’s important to note that in a series circuit, the current remains the same throughout the circuit, while the voltage drops across each component. In a parallel circuit, the voltage remains the same across all components, while the current splits among the different paths.
Overall, understanding electric current and circuits is fundamental to the study and application of electrical engineering and electronics. It allows for the design and analysis of various electrical systems and devices.
