Electrical Power and Series vs. Parallel Circuits
- The power consumed by a resistor (like a bulb) is given by the formula:
P = V2 / R
- In a series circuit, the voltage is divided among the components, whereas in a parallel circuit, each component gets the full voltage of the battery.
EXPLANATION:
- To make the bulb glow the most, it must receive the maximum voltage possible, as power is directly proportional to the square of the voltage (P ∝ V2).
- In a parallel circuit, each branch gets the full voltage of the battery. This means the bulb will receive the full voltage and thus, will glow the most.
- If the bulb is in series with other components, the voltage is divided among them, reducing the voltage across the bulb.
Therefore, in a parallel circuit configuration, the bulb would glow the most.
