## Can you put different wattage bulbs together?

Yes, you certainly can use bulbs of different wattages in your fixture. The fact that one socket pulls more current is not important. Bulb size is mostly a matter of light distribution and heat management.

### Does bulb wattage have to match?

Modern fixtures reveal their wattage rating somewhere in the assembly—you just have to know how to look for it. Once you identify your fixture’s wattage rating, buy a lamp that matches or is below what’s listed. As long as you don’t go over the manufacturer’s recommended wattage, you’ll be safe.

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

60 W bulb
The resistance of the bulb is given by R=V2/P. 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.

Do bulbs connected in series have the same brightness?

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.

## Can you use different light bulbs in the same fixture?

You can use LED and Incandescent bulbs in the same fixture, but it’s not recommended. It can cause the LED lights to flicker, or damage the LED bulbs or bulb fixture if it’s much older. Using matching bulbs in a fixture is always recommended for practical as well as aesthetic reasons.

### Can I use a 40 watt LED bulb in a 25 watt lamp?

The answer is YES. You can use an LED bulb having a higher wattage equivalent than your fixture allows — provided the LED bulb consumes less wattage than the fixture.

How bright is a 23 watt LED bulb?

A 1600-lumen LED bulb is the equivalent brightness for the 23-watt CFL bulb.

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

Answer. When these bulb are connected in series than current in both bulb is same, and Watt consumed can be given as i^2 x R, as Resistance of 60 W bulb is more than 100W bulb, so it will consume more power and glow brighter than 100W bulb.

## When a 60w 220v bulb and a 40w 220v bulb are connected in series then which bulb will glow brighter?

Answer. 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.

### Which light bulb is brighter 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.

Why do bulbs dim in a series circuit?

Why bulbs in series are dimmer The current going through them is smaller because two bulbs in series have a higher resistance than a single bulb. Each charge only gives up some of its energy in each bulb, i.e. the p.d. across each bulb is smaller.

How much current does a light bulb produce in series?

With fresh light bulbs, direct measurement with an ammeter shows that the actual current flowing in the parallel circuit is 0.34 A for one bulb, 0.68 A for two bulbs and 1.02 A for three bulbs, and in the series circuit it is 0.196 A.

## What does wattage rating mean on a light bulb?

Sure. The wattage rating for bulbs tells you about how many watts of power they draw if connected directly to a standard 115 V (or so) power supply. The power is equal to the current I times the voltage V.

### How many Watts Does It take to light a light bulb?

When the bulbs are connected in parallel, each bulb has 120 V across it, each draws 1/3 A, and each dissipates 40 watts. In this circuit, all bulbs glow at their full brightness. The total power dissipated in the circuit is three times 40, or 120 watts (or 3(1/3) A × 120 V = 120 W).

What is the voltage drop across each light bulb in series?

In the series circuit, any current that flows through one bulb must go through the other bulbs as well, so each bulb draws the same current. Since all three bulbs are 40-watt bulbs, they have the same resistance, so the voltage drop across each one is the same and equals one-third of the applied voltage, or 120/3 = 40 volts.
