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.

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.

Does wattage increase in parallel?

Connecting resistors in parallel or series does not change the wattage ratings of individual resistors used. Because resistors can collectively carry more current when they are wired in parallel, they can collectively dissipate more power, given an increase in current.

Which bulb will glow brighter when connected in 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 60W 220v bulb and a 40w 220v bulb are connected in series then which bulb will glow brighter?

Always, when two bulbs of the same voltage and different wattages are connected in series, the lower wattage bulb will glow brighter. There is no question that the 40w bulb has a higher resistance than the 60w bulb; so the 40w bulb will dissipate more wattage and therefore be brighter.

When two lamps of rating 40 W and 60 W are connected in series which bulb glows brighter?

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.

When a 60W 220v bulb and a 100W 220v bulb are connected in series then which bulb will glow brighter?

The resistance of the bulb is given by R=V2P. 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.

What happens when two 60 watt bulbs are connected in series?

We can see that 40w bulb have a high resistance and a 60w bulb. Thus 40w bulb will have a high power dissipation tha a 60w bulb. Hence 40w bulb will glow brighter. Originally Answered: Two bulbs of 60 watt and 40 watt are connected in series with a single source.

What is the resistance of a 40-watt bulb?

Assuming an incandescent bulb (a purely resistive load) and American household power of 120V, the 40 watt bulb in normal circumstances will draw 1/3 of an amp (P=VI so 40 = 120 * I, I=40/120=1/3) and thus it has a resistance of 360 Ohms (V=IR, 120 = 1/3 * R, R=360). Similarly, the 60 watt bulb will draw 1/2 an amp and has a resistance of 240 ohms.

Which light bulb will glow brighter 60W or 40W?

Thus 40w bulb will have a high power dissipation tha a 60w bulb. Hence 40w bulb will glow brighter. Originally Answered: Two bulbs of 60 watt and 40 watt are connected in series with a single source. Which bulb will glow more brighter and why?

How many light bulbs are there in a 220 volt circuit?

Three light bulbs of 40W, 60W and 100W are connected in series with 220 volt source. Which of the bulbs will grow brightest? Three light bulbs of 40W, 60W and 100W are connected in series with 220 volt source.
