Honestly, this is a homework question. A screenshot of it is given below:
Okay these are the things I have done in order to take the answer.
- First I calculate the equivalent resistance which comes form 1000 ohms and 10 ohms.
- Therefore I assume that total resistance of the circuit is increasing.
- And since the potential difference is constant for the equivalent resistance, I get the relationship of current is indirectly proportional to resistance by using Ohm's law.
So according to my argument a graph should indicate a decrement of current with distance PQ, but here in the answer I don't have such a thing. So I think I have done something wrong, so that is why I'm asking this question here!
