Exicom Trainee Mechanical Engineer Interview Questions and Answers

SOC refers to the state of charge of a battery, SOH refers to the state of health, pre-charge is the initial charging process, and cell chemistry refers to the type of chemicals used in the battery.

• SOC is the amount of charge remaining in a battery, expressed as a percentage of its maximum capacity.

• SOH is a measure of a battery's overall health and its ability to hold a charge over time.

• Pre-charge is the initial chargi...read more

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
