Two resistances are connected separately to a battery each will have
same current flow through them when connected in series
Resistance:
The correct option (D)
When two resistances are connected in series, the current through them will be the same, but the voltage drops across them will be different.
hence option D is correct.
The incorrect options (A), (B), (D)
Option(A)
When two resistances are connected in series, the current through them will be the same, but the voltage drops across them will be different.
Hence option A is incorrect.
Option (B)
The voltage across each resistor when two resistors are connected in parallel is the same.
The two resistors divide the battery current equally. The current flowing through a resistance determines its size.
Hence option B is incorrect.
Option(C)
The potential difference across the endpoints of two parallel resistances is the same, but the current flowing through them will be different.
Hence option C is incorrect.
Therefore the correct option is D.
