- Q1. What does a stress-strain diagram look like?
- Ans.
A stress-strain diagram shows the relationship between stress (force applied) and strain (resulting deformation) in a material.
The diagram typically starts with a linear elastic region where stress is directly proportional to strain.
After the elastic limit, the material enters the plastic region where it deforms permanently.
Finally, the material reaches its ultimate strength before failure occurs.
Examples of stress-str...

- Q1. What is Circuit breaker and give real life example
- Ans.
A circuit breaker is an electrical switch designed to protect an electrical circuit from damage caused by excess current.
Circuit breakers automatically interrupt the flow of electricity when a fault is detected.
They are commonly used in homes to protect electrical circuits from overloads or short circuits.
A real life example of a circuit breaker is the one found in a circuit panel in a house, which trips when too much
- Q2. What is ohm's law
- Ans.
Ohm's law states that the current flowing through a conductor is directly proportional to the voltage across it, given a constant resistance.
Ohm's law is represented by the formula V = IR, where V is voltage, I is current, and R is resistance.
It is named after German physicist Georg Simon Ohm.
It is commonly used in electrical engineering to calculate current, voltage, or resistance in a circuit.
For example, if a circui...

- Q1. Basic electrical questions
- Q2. Explain Ohms law, basic current voltage
- Ans.
Ohm's law states that the current flowing through a conductor is directly proportional to the voltage applied across it, with resistance as a constant factor.
Ohm's law is expressed as V = IR, where V is voltage, I is current, and R is resistance.
It can also be written as I = V/R or R = V/I.
For example, if a circuit has a voltage of 12V and a resistance of 4 ohms, the current flowing through it would be 3A (12V/4ohms =

- Q2. Torque equation of induction and explain
- Ans.
The torque equation of induction is used to calculate the torque produced in an induction motor.
The torque equation of induction is given by T = (3 * V^2 * R2) / (s * X2)
Where T is the torque, V is the voltage, R2 is the rotor resistance, s is the slip, and X2 is the rotor reactance
This equation helps in understanding the relationship between voltage, resistance, reactance, and slip in determining the torque produced i
