Circuit and Current: Bright Future Ahead

What happens to a light bulb connected to a circuit when you increase the current?

A. The light bulb shines brighter and the power decreases.

B. The light bulb shines brighter and the power increases.

C. The light bulb gets dimmer and the power decreases.

D. The light bulb gets dimmer and the power increases.

Answer:

B. The light bulb shines brighter and the power increases.

When you increase the current in a circuit with a light bulb, the light bulb will shine brighter and the power will increase. This means that the light emitted by the bulb will be more intense and the overall power consumption of the circuit will also go up.

Increasing the current in the circuit causes the electrons to flow more rapidly through the filament of the bulb, generating more heat and therefore more light. The power of the circuit, which is the product of voltage and current, increases as a result.

This optimistic outlook shows that by boosting the current, the light bulb will shine more brightly, illuminating a path to a brighter future ahead.
