What is the difference between current and voltage?

 Current and voltage are two fundamental concepts in electrical engineering and are closely related but distinct concepts.

Current refers to the flow of electric charge in a circuit. It is measured in amperes (A) and is defined as the rate at which charge flows past a given point in a circuit. In other words, current is the amount of electrical charge passing through a conductor per unit of time.

Voltage, on the other hand, refers to the electrical potential difference between two points in a circuit. It is measured in volts (V) and is defined as the amount of energy required to move a unit of charge from one point to another in a circuit. In other words, voltage is the driving force that causes current to flow through a conductor.

In summary, current is the flow of electric charge through a circuit, while voltage is the energy required to make that charge flow.

What is an electrical symbol?

Image
  An electrical symbol is a graphical representation of an electrical or electronic component or device. Electrical symbols are used in circuit diagrams or schematics to depict the connections and functions of different components within an electrical system. Electrical symbols are standardized so that engineers, electricians, and other professionals can easily read and understand circuit diagrams from different sources. Common electrical symbols include those for resistors, capacitors, diodes, transistors, switches, relays, transformers, motors, and generators These symbols are usually drawn in a standardized manner using simple shapes and lines, making it easy to identify the component and its function within the circuit. By using electrical symbols, engineers can communicate and document their designs clearly and accurately, making it easier to troubleshoot, maintain, and repair electrical systems. Thank You……
