Answer Posted / Sarvendra Kumar Rahul
Time Constant (τ) is a critical concept in electrical circuits. It represents the time required for an exponential decay or response to reach 63.2% of its final value. The time constant is calculated by multiplying the resistance (R) by the capacitance (C). Time constant has significance as it determines the rate of rise and fall of the voltage across a capacitor in various circuits, such as RC circuits. For example, in an RC circuit, if the time constant is small, the response will be fast, whereas if it is large, the response will be slow.

A 15 kw squirrel cage motor having a maximum efficiency of 90% on a continuous full load has temperature rise of 42 degrees celcius after 30 min and 52 degrees celcius after 1 hr under the above operation conditions. a) calculate its final steady state temperature rise on continuous load and the heating time constatnt. b) if the motor is operated on a short load for 9 min estimate its temperature rise. c) calculate the maximum overload that can be applied on a short, 9 min rating so that the temperature rise is the same as the final steady state temperature rise on continuous load.
