Can you tell if a light bulb is not lit?

Can you tell if a light bulb is not lit?

How to tell if a light bulb is half full?

Is there a comma after the final speech Mark?

If there is a reporting clause, then there is often a comma before the final speech marks: “I think we should go inside now,” said Molly. There is usually a full stop after the reporting clause.

Do you first need to find the resistance of each bulb?

Direct link to neelshaan2004’s post “Actually, we first need to find the resistance of …” Actually, we first need to find the resistance of each bulb, then find the equivalent resistance of all the resistors, THEN we find the current flowing through the entire circuit.

How is the power dissipated in light bulbs?

Direct link to ash’s post “Both the bulbs get the same amount of current flow…” Both the bulbs get the same amount of current flow. Then consider the following cases : CASE 2 BULB WITH LOW POWER – Since the power required is less even a lower current will just be enough to make it glow brighter. This is my logic.

Why does a light bulb have a lower power rating?

The one with a LOWER po…” The main reason is that.. The one with a LOWER power rating requires less energy as compared to the bulb with a HIGHER power rating (Which requires higher power to glow as bright.) But since the current is equal the one with the lesser power rating will glow brighter.
