Question

In an rc circuit, what is the name of the quantity represented by the symbol τ?

Answer 1

τ represents time constant

Step-by-step explanation:

In a RC circuit r is resistance and c is capacitance, generally capacitor is added in parallel connection with resistance Here time constant is equal to multiple of resistance and capacitor. RC circuit is also used for filtering of signals by blocking some specific frequency signals. Here RC is time constant and measured in seconds.

Answer 2

For a given resistance value or for a given capacitance value, the time rate at which a capacitor is charged or discharged is affected.
Therefore, the product of the value of the resistance for the value of the capacitance is what is called the "time constant"
It is represented with the Greek letter "tau" τ
τ=R*C
