Can you explain the function of resistor in LCR and RC circuit? Why time constant is taken only at o.36q in decay and 0.64 in growth of charge?

*Asked Kiran*

Answer:

We are studying the circuit containing a resistor and a capacitor. Further in almost all circuits there will be a resistance.

For the second part, you can easily see that **decaying to 36%** is same as **decaying by 64%**. Therefore the change that has taken place is same in both growth and decay.
