Question
In parallel combination of resistances ______.
Options
p.d. is same across each resistance
total resistance is increased
current is same in each resistance
all of the above are true
Solution
In parallel combination of resistances p.d. is same across each resistance.
Explanation:
In parallel combination, the ends of each resistor are connected to the ends of the same source of potential. Thus, the potential difference across each resistance is same and is equal to the potential difference across the terminals of the source (or battery).
