Q2. What is the ohms 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 of the conductor.
• 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 relationship between voltage, current, and resistance in an electrical circuit.

• For example, if a circuit has a vol...read more

Q5. By what is the speed of turbine controlled?
Ans. 
The speed of a turbine is controlled by adjusting the flow of steam or water.
• The speed of a turbine can be controlled by adjusting the flow rate of the working fluid, such as steam or water.

• By increasing or decreasing the flow rate, the turbine's speed can be increased or decreased accordingly.

• This control mechanism allows for efficient operation and optimization of power generation systems.

• For example, in a steam turb...read more
