Add your answer
Q2. What is time constant of RC circuit
Ans. 
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

Q1. What are comparators? Draw band pass filter circuit
Ans. 
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

Q1. What is the difference between star and delta connection.
Ans. 
Star and delta are two types of connections used in three-phase systems.
• Star connection has neutral point and is used for small loads.

• Delta connection has no neutral point and is used for high loads.

• Star connection has lower voltage and higher current while delta connection has higher voltage and lower current.

• Star connection is more reliable and easier to maintain than delta connection.
