Exicom DET 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

Inverters convert DC power to AC power, while UPS systems provide backup power during outages.

• Inverters convert direct current (DC) to alternating current (AC) to power electronic devices.

• UPS systems provide backup power during outages by switching to battery power when the main power source fails.

• Inverters are commonly used in solar power systems to convert DC power from solar panels to AC power for use in homes or bu...read more

Types of inverters commonly used in India include grid-tied inverters, off-grid inverters, and hybrid inverters.

• Grid-tied inverters are connected to the utility grid and do not require batteries.

• Off-grid inverters are used in standalone systems and require batteries for energy storage.

• Hybrid inverters can work both on-grid and off-grid, combining the features of grid-tied and off-grid inverters.

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
