@JohnRennie: In the simple circuit, I discussed above, the following are the questions, point by point.
1. In the circuit I discussed above, would the electric field inside the ideal wires be zero?
2. If the electric field inside the ideal wires is zero then what is the cause behind it? Is it due to the charge accumulation across the resistance, such that it cancels the electric field completely due to the external battery?
3. Why the charge accumulates across the resistance? I have following hypothesis. Kindly comment.
