When 25 W and 100 W bulbs are connected in series the 25 W bulb glows brighter?

25W bulb has more resistance (R=V2P) compared to 100 W bulb. Hence, it will glow brighter.

What happens when a 100 watt bulb and 60 watt bulb are connected in a series?

So the resistance of 60 W bulb is more than the resistance of 100 W bulb. When they are connected in series the current through both bulbs is same. Hence 60 W bulb will be more brighter because P = I2R.

Which bulb will glow brighter a 40 watt or a 100 watt in series?

From the relation P=(I*I) R since current is same we can say that power dissipation will be higher for the bulb with higher resistance i.e. 40W bulb. Hence 40W bulb will glow brighter in series connection. 2. When connected in parallel: In a parallel connection, voltage across each element is same.

Which bulb glow brighter 60w or 100W?

Answer: The bulb rated at 100 W will be brighter. When both bulbs are connected to the rated voltage, they will dissipate the rated power. The brightness of a bulb depends on the power it dissipates, so the 100 W bulb will be brighter than the 60 W bulb.

Which bulb glow brighter 60w or 100w?

What is the difference between a 60 watt light bulb and 100 watt?

Explanation: 100 watt bulb is used for 10 hours will consume 1000 wattsr. since 60 watt bulb consumes less power its light out put will be also less. Supply voltage being constant the more watts means more current,So you consume more energy pay for money.

Is 100W brighter than 60W?

Here is a breakdown of traditional watt light bulbs and the amount of light they produce in lumens: 40-watt bulb produces 450 lumens of light. 60-watt bulb produces 800 lumens of light (most widely used in households) 100-watt bulb produces 1,600 lumens of light.

Which bulb glow brighter 60W or 100W?

Why is a 25 watt bulb brighter than a 100 watt bulb?

In parallel the voltage is same across the two and current through the 25 watt bulb will be less than that of 100 watt bulb as it’s resistance is high. HENCE the bulb with power resistance will glow brighter i.e the 100 watt bulb.

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 power dissipation of a 100 watt bulb?

Power dissipated by Bulb 1 (80W) as voltages are same in the parallel circuit. IT = I1 + I2 = 0.364 + 0.455 = 0.818A Again proved that 100W bulb is greater in power dissipation than the 80W bulb when connected in parallel. Hence, 100W bulb will glow brighter than 80W bulb when connected in parallel.

What happens if two bulbs are connected in series to 220?

Two bulbs rated at 25w,110v and 100w,110v are connected in series to a 220v supply. What will happen to the circuit? The lower power bulb will get very bright for a very short time, then both bulbs will turn off and no current will flow.
