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

Contents

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 series?

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 will glow brighter in a series?

The bulb which dissipates more power will glow brighter. In series, both bulbs have the same current flowing through them. The bulb with the higher resistance will have a greater voltage drop across it and therefore have a higher power dissipation and brightness.

When a 40 W and a 100 W bulbs are connected in series then 40 W bulb will glow brighter than 100 W bulb?

Since lamps connected in series, the current flows through both the bulb is same. Let the current flowing through them is I. As R40 > R100, the power dissipated across 40 W is greater than 100 W. Hence 40 W bulb will glow brighter in series connection.

When a 60W bulb is connected in series to the 40W bulb which bulb glows more brightly?

The 10W bulb will be brighter. 1. When connected in series: In a series connection, current flowing across each element is same. So when 40W bulb and 60W bulb are connected in series, same current will flow through them.

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.

Why does a 100 watt bulb gives more light than a 60 watt bulb?

This is because of a derivation of Ohm’s law: Power = I^2*R. Being in series, the I^2 term is the same for both bulbs. So the power of each bulb is in proportion to its resistance. The resistance of the 60W has to be greater than the 100W, and therefore it is brighter.

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.

Are bulbs brighter in series or parallel?

Two light bulbs on the same series circuit share the voltage of the battery: if the battery is 9V, then each bulb gets 4.5 volts. … 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 makes each bulb glow?

The typical incandescent light bulb contains a thin wire (usually tungsten) called a filament that has a high electrical resistance. This filament gets very hot when an electric current passes through it. The intense temperature makes the filament glow brightly.

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.

How does the brightness of the bulbs change as you increase the number of light bulbs in the circuit?

Increasing the number of bulbs in a series circuit decreases the brightness of the bulbs. In a series circuit, the voltage is equally distributed among all of the bulbs. Bulbs in parallel are brighter than bulbs in series.

What’s the difference between 40 and 60 watts?

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)

Which bulb will glow brighter Quora?

The bulb which has the higher resistance will produce more heat and consequently will glow brighter. 40W bulb had the higher resistance hence it will glow brighter.

Which bulb is brighter daylight or bright white?

The Range of Color Temperature of Different Light Bulbs

The three primary types of light bulb color temperature are: Soft White (2700K – 3000K), Bright White/Cool White (3500K – 4100K), and Daylight (5000K – 6500K). The higher the Degrees Kelvin, the whiter the color temperature.
