When two lamps one rated 220v 50W and the other rated 220v 100W are connected in series with mains of 220v explain why does the 50W lamp glow brighter?

If the two lamps are connected in series with the mains, same current will flow through each lamp. From relation H = I2Rt, since resistance of 50W lamp is more than that of 100W lamp, so the 50 W lamp will consume more electrical energy than that of 100W lamp, in the same time. Hence the 50W lamp will glow more.

What does 100W bulb mean?

100 Watts on a bulb means it consumes 100 Watts of power when it is on. If it works for one second it will have consumer 100 Watt seconds of energy. If left on for an hour it will have consumed 100 Watt hours of energy.

Which one glows brighter if two bulbs of power 60w and 100W connected in parallel to a supply of 220v?

Answer: In serial connection, the total current in the circuit is a constant. Thus which ever will have a higher potential through will glow brighter. thus 100 W will have higher resistance and since V = IR hence will glow brighter.

What’s brighter 40w or 60w?

40-watt bulb produces 450 lumens of light. 60-watt bulb produces 800 lumens of light (most widely used in households) 75-watt bulb produces 1,100 lumens of light.

What happens if a 60W bulb and a 100W bulb are connected?

Originally Answered: If a 60W bulb and a 100W are connected In series in a circuit across which bulb will there be a greater voltage drop; how abt if they are in parallel? Voltage drop across any components in series is proportional to its resistance. 60W bulb has higher resistance than 100W bulb if both the bulbs were rated for same voltage.

Why does a 100 watt bulb glow brighter in a parallel circuit?

Now more current will flow in the bulb which has less resistance which is 100W bulb this time which means 100W bulb dissipate more power than 80W bulb (P=I2R) where current and resistance are directly proportional to the power. Hence, 100W bulb will glow brighter in a parallel circuit. How to know if Bulbs are Connected in series or Parallel?

What is the difference between a 100 watt and 50 watt bulb?

The 100 Watts bulb will have lower resistance than the 50 watts bulb so that it can take more current and produce more light. Now that both are in series what ever current flows flows through both the bulbs. Since the current is same through both the bulbs and 50 watts bulb has more resistance it will have more voltage as well.

What is the voltage drop across a 60-watt bulb?

Voltage drop across any components in series is proportional to its resistance. 60W bulb has higher resistance than 100W bulb if both the bulbs were rated for same voltage. So higher voltage drop will be across a 60W bulb.
