When the voltage supply connected. The capacitance of the capacitor will become k times
∴C′=kC =6×17.7= 106.2 pF
the potential difference =100V.
∴ Charge on the capacitor
q′=C′
V=106.2× ×100 =106.2× q
∴C′=kC =6×17.7= 106.2 pF
the potential difference =100V.
∴ Charge on the capacitor
q′=C′
V=106.2× ×100 =106.2× q
