Q7. Explain Joule law's and Newton's laws
Ans. 
Joule's law relates to the heat produced by a current passing through a resistor, while Newton's laws describe the relationship between an object's motion and the forces acting on it.
• Joule's law states that the heat produced by a current passing through a resistor is directly proportional to the square of the current and the resistance of the resistor. It can be expressed as Q = I^2 * R, where Q is the heat produced, I...read more

Q8. Explain Boyle's law
Ans. 
Boyle's law states that the pressure of a gas is inversely proportional to its volume at a constant temperature.
• Boyle's law can be mathematically expressed as P1V1 = P2V2, where P represents pressure and V represents volume.

• This law is based on the assumption that the temperature remains constant.

• As the volume of a gas decreases, its pressure increases, and vice versa.

• Boyle's law is commonly used in various fields such

Q2. Why transmission was in high voltage.
Ans. 
Transmission is in high voltage to reduce energy losses and increase efficiency.
• High voltage reduces energy losses during transmission

• Lower current at higher voltage leads to lower resistive losses

• Efficiency of transmission lines increases with higher voltage

• High voltage allows for long distance power transmission with minimal losses
