- Meaning of a battery being 2.5 V 1 answer
What does it mean by a battery is of 1.5 Volt ? Does it mean that it would take 1.5 Joules of energy to transfer -1 columb of charge from the negative end to the positive end of the battery ?
What is the reason for it to take 1.5 Volt of energy to transfer the charge - is it needed to do work to move the charge against the electric field generated by the positive and negative sides of the battery ? Then would the Volt increase if the distance between the positive and the negative sides are increased (as it would have to do more work against the field)?
Then if you join a broken piece of wire to one side and a broken piece of wire to another side of the battery, why the potential difference between the two ends of the battery is still 1.5 Volt ?
