The discussion revolves around understanding the brightness of light globes in series circuits, specifically focusing on the effects of switching individual globes Sa and Sb on and off. Participants are exploring the implications of these actions on total resistance and current distribution within the circuit.
The discussion is ongoing, with some participants clarifying their understanding of the effects of closing each switch. There is a mix of interpretations regarding current flow and resistance, with some guidance provided on the behavior of current in parallel circuits. No consensus has been reached yet.
Participants are working under the assumption that no additional information or equations are provided, which may limit the depth of their analysis. The nature of the circuit configuration is also a point of contention, particularly regarding the concept of short-circuiting.
It is not correct. Since the total resistance remains the same, the current drawn from the cell is the same. In both the cases , it equally branches out in two parallel circuits. So in each the branch the current is I/2.TyErd said:
One bulb is short circuited. Leaving that bulb, calculated the total resistance and the current in each bulb.TyErd said:
All the current passes through the Sb. So the bulb will be off.TyErd said:
