... Electric field at X is the smallest. (Try some numbers to get answer) 4. Statement (1) is correct, because terminal voltage is V = E – Ir, now a resistor is added in parallel, so equivalent resistance decreases, so current increases, so terminal p.d. decreases. Statement (2) is correct as explained ...
