hello this is vijay,
capacitor charges but time constant..is it 5*rc?

Yadwinder Singh said: (May 10, 2012)  
Time constant is RC seconds in which it reaches 63% of Max. voltage(Supply Voltage)

Yadwinder Singh said: (May 10, 2012)  
In 5RC it is nearly equal to supply voltage.
To get same voltage it requires infinite time.
