Q1. If there Hazzard is occur so what should we do first
Ans. 
The first thing to do in case of a hazard is to ensure the safety of yourself and others.
• Assess the situation to determine the nature and extent of the hazard.

• Alert others in the vicinity about the hazard.

• Follow safety protocols and procedures to mitigate the hazard.

• Contact emergency services if necessary.

• Evacuate the area if instructed to do so.

Q5. What is current
Ans. 
Current is the flow of electric charge in a circuit.
• Current is measured in Amperes (A).

• It is the rate of flow of electric charge past a point in a circuit.

• Current can be either direct current (DC) or alternating current (AC).

• In a series circuit, the current is the same at all points.

• In a parallel circuit, the total current is divided among the branches.

• Ohm's Law relates current, voltage, and resistance: I = V/R.

Q6. 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)

• Higher voltage means more potential energy available to move electrons

• Voltage can be DC (direct current) or AC (alternating current)

• Example: A battery provides a voltage of 1.5V to power a flashlight
