I connected a bulb to a battery positive terminals with positive and negative terminals with negative . It glows as it should but when i connect the positive terminal of the same bulb to the positive terminal of one battery and negative terminal of the same bulb to the negative terminal of another battery. The bulb does not glow.
What I want to ask here is that electric potential difference is being maintained then why does the bulb does not glow. NOTE : Batteries are not connected with each other. Both batteries are separately placed.
