Discuss the arcing phenomenon in a circuit breaker.

In the voltage-controlled square/triangular waveform generator circuit we covered, is the transistor switch able to pull its drain towards the smallest possible voltage when it is ON? Which regimes of operation would you expect the transistor switch to remain for longer time intervals during the operation of the circuit, and why? Explain.

What role does environmental testing play in assessing the reliability of electronic components?

Describe the operation of a circuit breaker in protecting a power system from faults.
