### What is the resistance of a 25 W bulb connected to 120 V AC?

580 ohms

Calculator Screenshots So the power is the voltage squared divided by its resistance and we can solve this for R by multiplying both sides by R over P and so resistance then is the voltage squared divided by the power. So that’s 120 volts squared divided by 25 watts, which is 580 ohms to two significant figures.

#### What do the markings on a light bulb mean?

Bulb Shapes and Sizes The code number of a bulb consists of a letter or letters followed by a number. The letter indicates the shape of the bulb and the number relates to the diameter of the bulb in eighths of an inch. The mosts commonly used household bulb is the A-19.

**How many watts is 120V light bulb?**

Line Voltage 120V, 42W – 60W, Light Bulbs | Lamps Plus.

**What does 120V mean on a light bulb?**

What voltage bulb should I use? The most common voltage for electric light bulbs is 120 volts (120V). This is the default voltage for most lighting fixtures. However, some lighting fixtures are low voltage. Low voltage lighting is more energy-efficient, but it requires low voltage bulbs to work.

## What is the resistance of a 100 W lightbulb in a 120 volt circuit?

For example, a 100 watt light bulb operating on 120 volts AC will have 144 ohms of resistance and will draw 0.833 Amps.

### What is the current when a 60w lamp is connected to 120v?

Explanation: Here power is 60 watts. voltage is 120 so voltage x 0.5 amperes will make the power 60 watts. current= 0.5 amperes.

#### How do I know how many watts my light bulb is?

Find the Wattage Rating of a Light Bulb All light bulbs, whether they are traditional incandescent bulbs, fluorescent bulbs (CFUs), or LED (light-emitting diode) bulbs will have a wattage rating printed somewhere on the glass or on the metal collar of the bulb.

**How do you tell what size a light bulb is?**

Bulb sizing is very straightforward and simple, it is based on the diameter of the bulb at its widest point, measured in eighths of an inch (⅛”). For example, the designation “T12” indicates a tubular bulb that is 12 eighths of an inch (12/8”) in diameter (or 1 ½”).

**How many watts is a 120V light bulb?**

## How many watts is in 120 volts?

Volts = Watts / Amps Examples: 2400 Watts / 20 Amps = 120 Volts.

### What voltage is a 60 watt bulb?

120 volts

Note – A light bulb rated at 60 watts at a voltage of 120 volts has a different filament resistance to consume 60 watts instead of 100. The filament in a 60 watt bulb has a resistance of 240 ohms as compared to 145 ohms for a 100 watt bulb. The above assumes that the voltage source is constant at 120 volts.

#### Is a 60 watt bulb 120 volts?

Sunlite, 60 watt incandescent medium based T10 tubular bulb works with most 120 volt lighting …

**What is the current in a 60 watt bulb plugged into a 120 volt outlet?**

0.5 A

The current in a 60-Watt bulb plugged into a 120-Volt outlet is 0.5 A.

**What is a 25 watt?**

25 Watts is a 2001 Uruguayan urban comedy drama film directed and written by Juan Pablo Rebella and Pablo Stoll. The independent film picture stars Daniel Hendler, Jorge Temponi, and Alfonso Tort.

## What is a 25 watt LED equivalent to incandescent?

A 5 to 25 watt LED lightbulb can give off the same brightness as a 40 to 100 watt lightbulb. Traditional incandescent light bulbs waste 90% of their energy by giving off much more heat than an LED bulb.
