The bulb glows dimly when current is passed through a vinegar solution because the small number of ions in the vinegar solution move through the filament of the bulb.
when electric current is passed through acidified water hydrogen gas is released at the cathode..

yes
yes it does
When an electric current is passed through Argon, it becomes blue
Lightning is a DC current and it will pass through your body with devastating effect. Defibrillators use a DC current to restart/reset your heart if it has stopped or gone into fibrillation. So DC current is passed through your body.
Primary current is a flow to be measured that cannot be safely passed through the measuring device. A current transformer is used to provide a lower level, secondary current that can be passed safely through the measuring device. Primary current is measured as a secondary current, multiplied by the turns ratio in the current transformer.

The carbon rods have electrical resistance. Thisi causes them to heat when current is passed through them. The water gets heated by the carbon rods.
Yes ,due to heating effect of current.
