Which bulb will glow brighter a 40 watt or a 100 watt?
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.
Which bulb will glow brighter 60W or 100W in parallel?
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.
When a 40 W and a 100 W bulbs are connected in series then 40 W bulb will glow brighter than 100 W bulb?
In series, P=i2R and in parallel, P=V2R So 40W in series and 100W in parallel will grow brighter.
Will bulbs be brighter in series or parallel?
A parallel circuit avoids this problem. Two bulbs in a simple parallel circuit each enjoy the full voltage of the battery. This is why the bulbs in the parallel circuit will be brighter than those in the series circuit.
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.
When bulbs are connected in series the lower power bulb glows brighter?
When we connect two bulbs or more than two bulbs in the series, the bulb which has lower power rating have more resistance and it will glow brighter.
What makes each bulb glow?
Electricity flows through a thin wire in the light bulb called the filament. The filament used in a bulb has a property called “resistance.” … A filament has a lot of resistance to electricity. Therefore as a result of this, the filament heats up and starts glowing, converting electrical energy to light energy.
Why is one bulb brighter Why do two bulbs not glow?
Each bulb sees the full voltage when the bulbs are in parallel. When a bulb gets more power, it will glow brighter. The effective resistance of the circuit is reduced by the parallel combination of resistors. … It glows brighter.
