Q2. Type of smoke detectors.
Ans. 
There are two main types of smoke detectors: ionization and photoelectric.
• Ionization smoke detectors use a small amount of radioactive material to ionize the air and detect smoke particles.

• Photoelectric smoke detectors use a light beam to detect smoke particles in the air.

• Dual sensor smoke detectors combine both ionization and photoelectric technologies for more comprehensive detection.

Q1. HOW TO CALCULATE CT CURRENT
Ans. 
CT current can be calculated by dividing the primary current by the turns ratio of the current transformer.
• CT current = Primary current / Turns ratio

• Primary current is the current flowing through the primary conductor

• Turns ratio is the ratio of the number of turns in the primary winding to the number of turns in the secondary winding
