I have read about Series RC Circuit and have understood the Time constant concept.
Wikipedia states - "It is the time required to charge the capacitor, through the resistor, from an initial charge voltage of zero to approximately 63.2% of the value of an applied DC voltage, or to discharge the capacitor through the same resistor to approximately 36.8% of its initial charge voltage. "
Since Capacitor is charged through this resistor, the concept of time constant is valid.
But assume a parallel RC Circuit. I was not able to find the formula for time constant of a parallel RC circuit and also not sure whether the concept of time constant in a parallel RC circuit would mean something?
Can someone provide me the formula for Parallel RC Circuit during charging and discharging?
My question is based on the below circuit :
Once the voltage across the sense resistors cross 0.7V, the Transistor Q2203 will turn ON. What role does the C2202 play in combination with the sense resistors?
I have checked and reduced the value of C2202 in simulation and saw that if I decreased the value of C2202, the transistor turns ON quickly for a certain load resistance. If C2202 value is increased, the time taken for the Q2203 to turn ON increases? So, I thought of researching on charging of a parallel RC Circuit and its formulas which I couldn't find?
Please help me to solve my queries in the question.
