Answer
All of the above
Reason — For parallel combination of resistances :
- On I-V graph, the slope of line is more because resistance in parallel combination is less than series combination.
- The potential difference across each resistance is same because, the ends of each resistor are connected to the ends of the same source of potential.
- According to Ohm's Law V = IR. Hence, the current in a resistor is inversely proportional to the resistance.
