Q1. What is draft angel & Shutoff and Difference
Ans. 
Draft angle is the angle of the vertical wall of a mold or part, while shutoff is the point where two mold halves meet to prevent material flow.
• Draft angle is necessary for easy ejection of parts from molds.

• Shutoff is crucial for preventing material leakage and ensuring part accuracy.

• Draft angle is typically around 1-3 degrees, while shutoff is a precise meeting point of mold halves.

• Examples: Draft angle - plastic inje

Q1. What is the relay
Ans. 
A relay is an electrically operated switch that uses an electromagnet to mechanically operate a switch.
• Relays are used to control high power circuits with low power signals

• They are commonly used in automotive, industrial, and household applications

• Relays can be classified based on their operation, such as electromechanical relays or solid-state relays

Q2. Ohm's law and current
Ans. 
Ohm's law states that the current flowing through a conductor is directly proportional to the voltage across it, given constant resistance.
• Ohm's law equation: V = I * R (voltage = current * resistance)

• Current is the flow of electric charge through a conductor

• Higher voltage leads to higher current flow, given constant resistance

• Lower resistance leads to higher current flow, given constant voltage
