Cummins Electrical Maintenance Supervisor Interview Questions and Answers

Time constant of an RC circuit is the time taken for the voltage across the capacitor to reach approximately 63.2% of its final value.

• Time constant (τ) is calculated as the product of resistance (R) and capacitance (C) in the circuit, τ = R * C.

• It represents the rate at which the capacitor charges or discharges in response to a step change in voltage.

• A smaller time constant indicates a faster response of the circuit, w...read more

Comparators are electronic circuits that compare two voltages and output a digital signal based on the comparison. Band pass filter circuit allows only a certain range of frequencies to pass through.

• Comparators are used in applications such as voltage level detection, waveform shaping, and pulse width modulation.

• They have two input terminals for the voltages to be compared and one output terminal for the digital signal...read more
