**Diagram Description:**
The image displays a simple electrical circuit diagram featuring light bulbs and a battery.
- The bulbs are labeled from A to L.
- The battery is depicted on the left side, connecting to bulb A in series.
- Bulbs C and D are parallel to bulb A.
- Further, bulb E is in series with bulb C, and bulb F is in series with bulb D.
- Bulbs G and H are connected parallel to each other but in series with bulbs C-E and D-F.
- Bulbs K and L are parallel and connected at the bottom, leading back to the battery.
**Questions:**
1. Which of the light bulbs (if any) do NOT light up because they have negligible current?
2. Which of the light bulbs (if any) are connected in series to each other?
3. If each light bulb has a resistance R, what is the effective or equivalent resistance of the circuit in terms of R?
Expert Solution
Step 1
1) A wire is connected in parallel to bulb G.
Since resistance of wires is negligible, hence, most of the current flows through it and negligible current flows through bulb G.
2) Bulbs which are connected in series are as follows:
(i) A and B
(ii) C and D
(iii)E and F
