capacitor is discharged, the current will be highest at the start. This will gradually decrease until reaching 0, when the current reaches zero, the c pacitor is fully discharged as there is no charge stored across it.The rate of decrease of the potential difference an the charge will again be proportional to the value o
A gas discharge tube is a bulb or tube (usually glass), with two (or more) electrodes inserted into it, that has been evacuated and filled with a gas or gas mixture usually at somewhat less than atmospheric pressure.
Their high surge-current rating provides an enhanced level of voltage limiting during fast-rising events while maintaining a compact size. These two-electrode, high-voltage gas discharge tubes offer high insulation resistance and are available in a DC sparkover voltage range of 1 kV to 3.3 kV with a 5 kiloampere (kA) surge-current rate.
capacitor is equal to the potential difference across the battery. Because the current changes throughout charging, the rate of flow of charge will not be linear.At the start, the current will be at its highest but will graduall decrease to zero. The following graphs summarise capacitor charge. The potential diffe

This process will be continued until the potential difference across th capacitor is equal to the potential difference across the battery.
