Two resistors of resistance 2 Ω and 4 Ω when connected to a battery will have
(a) same current flowing through them when connected in parallel
(b) same current flowing through them when connected in series
(c) same potential difference across them when connected in series
(d) different potential difference across them when connected in parallel
Answer: (b)
Solution:
In series combination, same current flows in both the resistors but voltage gets split according to resistance value.
In parallel combination, current splits and voltage remains same across the resistors.
Therefore, option (b) is correct.
