Q2. Process of Iron and Steel making
Ans. 
Iron and steel making is a process of extracting iron from iron ore and converting it into steel through various methods.
• Iron ore is first mined and then processed to remove impurities and create iron concentrate.

• The iron concentrate is then smelted in a blast furnace to produce pig iron, which contains high amounts of carbon.

• Pig iron is further processed in a basic oxygen furnace or electric arc furnace to remove exce...read more

Q2. Explain Freaday law
Ans. 
Freaday's law states that the induced electromotive force (emf) in any closed circuit is equal to the negative rate of change of the magnetic flux through the circuit.
• Freaday's law is a fundamental principle in electromagnetism.

• It explains how a changing magnetic field can induce an electric current in a circuit.

• The induced emf is proportional to the rate of change of the magnetic flux.

• Mathematically, the equation for ...read more

Q3. Explain ohm law
Ans. 
Ohm's Law states that the current flowing through a conductor is directly proportional to the voltage across it and inversely proportional to the resistance.
• Ohm's Law is represented by the formula V = I * R, where V is voltage, I is current, and R is resistance.

• It helps in calculating the current flowing through a circuit when the voltage and resistance are known.

• It also helps in determining the resistance in a circuit...read more
