Question
In a network as shown in the figure, the potential difference across the resistance 2R is (the cell has an emf of E volt and has no ingternal resistance)
- 2E
- E
The correct answer is:
In the given circuit, resistors 4R and 2R are connected in parallel while resistance R is connected in series to it.
Hence, equivalent resistance is
Given, emf is E volts, therefore
Potential difference across R is
Potential difference across 2R is
