Respuesta :
The value of the voltage across the capacitor at the end of three time constants is 5.97 V.
What is electric potential energy of a capacitor?
The electric potential energy of a capacitor is the energy stored by it.
It is given that the fully charged capacitor with a voltage of 120 v is discharged through a resistor.
Here, the time T is three times to the time constant. The value at this point, the potential difference around the capacitor, equals the maximum potential.
The voltage across the capacitor at the end of three time constants is,
[tex]V=120\times e^{-3}\\V=5.97\rm \; V[/tex]
Thus, the value of the voltage across the capacitor at the end of three time constants is 5.97 V.
