A 10 watt bulb is defined by the voltage supply and the resulting current. So to make the math simple, suppose you have a 10 watt incandescent bulb designed to work at 20 volts. That means it will draw 1/2 amps.
Watts = Volts x Amps.
The resistance of the bulb is then Volts / Amps so in this case the resistance of the bulb would be 40 ohms.
So our mythical bulb has a resistance of 40 ohms with 20 volts across the bulb in our example. Now if we put two of these bulbs in series with the same 20 volts we now have a total resistance of 80 ohms supplied by 20 volts and the circuit will draw 1/4 amp. This lower current will cause the bulbs to be dimmer.

Does a 150 watt bulb do 150 joules of work?
Every second a 150 Watt bulb converts 150 Joules from electricity into heat and light. The number of Watts tells you how many Joules pass per second.
How much horsepower is in a 270 watt light bulb?
To convert watts to horsepower, you can use the conversion factor where 1 horsepower is approximately equal to 746 watts. Therefore, a 270-watt light bulb would have about 0.362 horsepower (270 watts ÷ 746 watts/hp). This is a very small amount of horsepower, as light bulbs are primarily designed for illumination rather than mechanical work.
How do you work out how many amps a forty watt bulb uses?
To calculate the amperage of a 40-watt bulb, you need to use the formula: Amps = Watts / Volts. If the bulb operates at 120 volts (standard for US households), the amperage will be 0.33 amps (40 watts / 120 volts).
How does human power output compare to the power output of a 60-Watt light bulb?
About the same for moderate work. Labourers can manage 100 watts continuously, while a horse-power is 746 watts.
Power ratings on a light bulb are?
indicated in watts and represent the amount of energy the bulb consumes. A higher wattage bulb will produce more light, but also consume more electricity. It's important to choose the right wattage for your lighting needs to balance brightness and energy efficiency.
What is the difference of a series connection and a parallel connection?
In a series connection, components are connected end to end, creating one path for current flow. In a parallel connection, components are connected side by side, creating multiple paths for current flow. As a result, the voltage is the same across components in a series connection, while the current is the same across components in a parallel connection.
What is prediction when one bulb removed in series connection?
It will all just turn off. Because with a series circuit the power travels through each light bulb in a series (one after another) so if it is interrupted by there being a burned out or removed bulb, the circuit will not be complete and thus not work at all. If you want to see for yourself, most Christmas lights are series circuits, go ahead and take one out.
Does a 150 watt bulb do 150 joules of work?
Every second a 150 Watt bulb converts 150 Joules from electricity into heat and light. The number of Watts tells you how many Joules pass per second.
How much work does a 100-watt light bulb do when it is lit for 30 seconds?
The work done by a 100-watt light bulb when lit for 30 seconds can be calculated using the formula work = power x time. Power = 100 watts, Time = 30 seconds. Work = 100 watts × 30 seconds = 3000 joules.
How would a lamp requiring a usb connection work?
The specification for USB connectors requires them to provide 5 volts at up to 500 mA. So about 2.5 watts. Thus it is possible to power a small LED light bulb with a USB lead.
What electrical connection will continue to work even if you take away one bulb?
parallel
Where would you put an ammeter in a circuit?
in a series circuit or it will not work. Put it after the bulb
How much horsepower is in a 270 watt light bulb?
To convert watts to horsepower, you can use the conversion factor where 1 horsepower is approximately equal to 746 watts. Therefore, a 270-watt light bulb would have about 0.362 horsepower (270 watts ÷ 746 watts/hp). This is a very small amount of horsepower, as light bulbs are primarily designed for illumination rather than mechanical work.
If a light bulb is missing in a series circuit will the bulb light?
If one light bulb in a series circuit fails, all the other light bulbs will go out, until the failed bulb is replaced and the series circuit is completed again.If one light bulb in a parallel circuit fails, all the other light bulbs will still work.
How do you work out how many amps a forty watt bulb uses?
To calculate the amperage of a 40-watt bulb, you need to use the formula: Amps = Watts / Volts. If the bulb operates at 120 volts (standard for US households), the amperage will be 0.33 amps (40 watts / 120 volts).

Why wont brake lights work on your 2003 Dodge Durango but all other lights work?
the bulb could be blown or a bad connection. find out if there is a current al the way to the bulb socket.
