Q1. What is electricity
Ans. 
Electricity is the flow of electric charge through a conductor.
• Electricity is a form of energy resulting from the existence of charged particles (such as electrons or protons).

• It can be generated by various means such as chemical reactions, electromagnetic induction, or solar panels.

• Electricity can be harnessed to power various devices and systems, from light bulbs to computers.

• It is essential for modern society, enabl...read more

Q2. What is voltage
Ans. 
Voltage is the difference in electric potential between two points in a circuit, measured in volts.
• Voltage is the driving force that pushes electric current through a circuit

• It is measured in volts (V)

• Voltage can be positive or negative, depending on the direction of current flow

• Higher voltage means more potential energy available to move electrons

• Examples: A battery provides voltage to power a flashlight, a wall outle

Q3. What is circuit
Ans. 
A circuit is a closed loop through which an electric current can flow.
• A circuit consists of components such as resistors, capacitors, inductors, and power sources.

• There are two types of circuits: series circuits (components connected in a single path) and parallel circuits (components connected in multiple paths).

• Circuits can be used to perform various functions such as amplification, filtering, and signal processing.

• E...read more

Q4. What is basic difference between current and voltage
Ans. 
Current is the flow of electric charge, while voltage is the force that drives the current.
• Current is the rate of flow of electric charge through a conductor.

• Voltage is the difference in electric potential between two points in a circuit.

• Current is measured in Amperes (A), while voltage is measured in Volts (V).

• Ohm's Law relates current, voltage, and resistance in a circuit: V = I * R.

• In a simple analogy, current is li...read more

Q5. What is the earthing used
Ans. 
Earthing is used in electrical systems to protect against electric shock and ensure proper functioning of equipment.
• Earthing is used to provide a path for fault currents to flow safely to the ground.

• It helps to stabilize voltage levels and prevent damage to equipment.

• Different types of earthing systems include TN, TT, and IT systems.

• Examples of earthing methods include rod earthing, plate earthing, and pipe earthing.
