What might variable resistors be used for in a cinema?
dimmers in cinemas or rooms
What shouldn't dimmers be used for?
Dimmers do not work well with florescent lights. The should only be used with incandescent bulbs.
What changed in dimmers manufactured after 1995?
The price.
Where can one find more information about Dimmers?
There are a few ways to find out more information about dimmers. You can talk to someone that works in electrical departments at Home Depot, Lowes, or local lighting stores. There is also an online site called How Stuff Works that explains about dimmers.
What is disease caused by thymine dimmers?
Xeroderma Pigmentosum
What are those materials of resistors?
most of the resistors commonly used are carbon resistors
What is a dimmer on the lighting console?
The dimmers control the intensity of the lights.
What is carbon composition resistors?
Carbon composition resistors are resistors that are made with carbon or graphite mixed with a binding material. It's one type of resistors among several. There are also carbon-film resistors and metal-film resistors. Out of all the resistors, carbon-film resistors have the greatest tolerances and changes to temperature fluctations. Thus, they are used in applications where precision isn't critical and where temperature will not change drastically.
How do you find the resistance of a series circuit with n identical resistors?
The total resistance of resistors in series is simply the sum of the resistance values of those resistors. If the resistors are identical, then you can multiply the resistance of one of them by the number of resistors in the circuit.
Who invented resistors?
Otis f.boykin invented resistors
What is the advantage of film resistors over carbon resister?
Film resistors have lower noise than carbon resistors.
What wavelength of uv light causes thymine dimmers?
UV-c
