Q1. What is OHMS Law and formula
Ans. 
OHM's Law states the relationship between voltage, current, and resistance in an electrical circuit.
• OHM's Law formula: V = I * R (Voltage = Current * Resistance)

• V = voltage (measured in volts)

• I = current (measured in amperes)

• R = resistance (measured in ohms)

• Example: If a circuit has a voltage of 12V and a resistance of 4 ohms, the current flowing through the circuit would be 3A (I = V / R = 12V / 4 ohms = 3A)

Q2. Deference between AC & DC
Ans. 
AC stands for alternating current, which changes direction periodically. DC stands for direct current, which flows in one direction.
• AC is commonly used in household appliances and power distribution systems.

• DC is commonly used in batteries and electronic devices.

• AC can be easily converted to different voltages using transformers.

• DC is more efficient for long-distance power transmission.

• Examples of AC devices include re...read more

Q3. Types of circuit breaker what are they
Ans. 
Types of circuit breakers include thermal-magnetic, magnetic, and hydraulic-magnetic.
• Thermal-magnetic circuit breakers combine thermal and magnetic mechanisms to provide overload and short circuit protection.

• Magnetic circuit breakers use a solenoid to trip the breaker when a fault is detected.

• Hydraulic-magnetic circuit breakers use a hydraulic delay to provide precise protection against overloads and short circuits.

Q3. Types of fits and advantages
Ans. 
Types of fits include clearance fit, interference fit, and transition fit, each offering different advantages.
• Clearance fit: allows for easy assembly and disassembly, used in applications where relative motion is required (e.g. sliding fits)

• Interference fit: provides a tight connection with no relative movement, used in applications where rigidity is important (e.g. press fits)

• Transition fit: offers a compromise betwee...read more

Q4. Expalain spring back effect in details
Ans. 
Spring back effect is the tendency of a material to return to its original shape after being deformed.
• Spring back effect occurs in materials like metals, plastics, and composites.

• It is caused by the release of internal stresses that were introduced during the forming process.

• Factors affecting spring back include material properties, forming process, and tooling design.

• Examples include metal sheets returning to their or
