[Solved] Of the two bulbs, one glows brighter than the other. Which b (2024)

I'm an enthusiast with a deep understanding of physics, particularly in the realm of electricity and circuits. Now, let's delve into the concepts discussed in the provided article:

The article discusses the concept of power in electrical circuits and how it is related to resistance. Here are the key points:

1. Power (P) in an electrical circuit:

   • Power is the rate of work done by an electric current.
   • Denoted by P, the SI unit of power is the watt (W).
   • Power dissipation is given by the formulas: ( P = V \cdot I ) and ( P = \frac{{V^2}}{{R}} = I^2 \cdot R ).

2. Ohm's Law:

   • Ohm's law states that ( V = I \cdot R ), where V is the voltage, I is the current flowing through the circuit, and R is the resistance.

3. Relation between Power and Resistance:

   • The formula ( P = \frac{{V^2}}{{R}} ) indicates that, keeping the potential difference (V) constant, power is inversely proportional to resistance (R).
   • A bulb drawing maximum power will glow more compared to others, and the current is inversely proportional to resistance.

4. Application to the Bright and Dim Bulbs:

   • The conclusion drawn in the article is that the dim bulb will have higher resistance, and the one glowing brighter will have less resistance.
   • Therefore, the answer to the question is "The dim bulb."

This understanding is crucial for comprehending electrical circuits, power consumption, and the behavior of different components like bulbs in a circuit. If you have any specific questions or if there's another topic you'd like to explore within physics, feel free to ask!
