Two resistors of resistance 2 Ω and 4 Ω when connected to a battery will have
- same current flowing through them when connected in parallel
- same current flowing through them when connected in series
- same potential difference across them when connected in series
- different potential difference across them when connected in parallel
In series combination of resistor, the current through both the resistor are same but potential difference across each will be different. In parallel combination current across each resistor will be different but the potential difference will be same.
The correct option is B.
