What is the current when a 100 Watt bulb is connected to your home outlet of 120 volts?

or current=100/120=0.833 amperes.

What is the current through a 75 Watt light bulb that is connected to 120 volts be careful?

current= watts divided by voltage= 75/120= 0.625 amperes.

What is the current through a 60 W lightbulb that is connected to a 120 V outlet?

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 you calculate the current in a light bulb?

We are given the voltage and the power output of a simple circuit containing a lightbulb, so we can use the equation P=IV to find the current I that flows through the lightbulb. 19.51P=IVI=PV=60 W120 V=0.50 A. Thus, a half ampere flows through the lightbulb when 120 V is applied across it.

How many Amps does a 100 watt bulb use at 120 volts?

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 through a 75 watt light bulb that is connected to a 125 volt outlet?

3. What is the current through a 75-W light- bulb that is connected to a 125-V outlet! 1 = SD = 75W 125 V = 0.60 A 15.

What is the voltage of a light bulb?

120 volts
The most common voltage for electric light bulbs is 120 volts (120V). This is the default voltage for most lighting fixtures.

What happens if you plug a 12 volt bulb into 120 volt?

On the other hand if you plug a 120 volt bulb into a 12 volt fixture the bulb will not turn on, and vice-versa is you plug a 12 volt bulb in a 120 volt fixture the bulb will be permanently damaged.

What is the angle of incidence of a light wave?

The angle of incidence of a light wave is diffraction A change in the direction of a wave as a result of its encountering a sharp edge or a slit is called ______________. refraction. The bending of light because of a speed change as it moves from one medium to another is called refraction

What are the three main characteristics of a light bulb?

Once you have the three main characteristics you are then able to match any of the secondary characteristic. The three main and most important characteristics you must match with the replacement bulbs are the lamps voltage, wattage and base. The secondary characteristics of your bulb are bulb shape, type, lumens, color temperature and life.

How do I select the correct bulb for my project?

You will need to start with the type of the bulb you are looking for (incandescent, halogen, LED, fluorescent etc.) then choose the shape (A, PAR, MR, etc.) and at this point use the refine option on the left to select the proper base, voltage and wattage of the bulb.
