Question

Two resistors of resistance $2\Omega$ and $4\Omega$ 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 1

The correct option is B

Same current flowing through them when connected in series

The explanation for the correct option:

Series connections:

1. In a series connection, the components are joined end to end.
2. When two components are connected in series, the potential difference across the resistor is different.
3. Since the current flows in a single path, the current flowing through the components is the same.

Parallel connection:

1. In a parallel connection, the components are connected along multiple paths.
2. In the case of the parallel connection, the potential difference across the two components is the same.
3. Since the current is divided into multiple paths, the same current does not flow across the components in a parallel connection.

Hence, option (B) is correct.
