Can you use a SCR instead of a relay to control output wattage of a heater?
Yes, using a method called phase control. This method is also used in dimmer switches to continuously reduce the brightness of lights.
What does a dimmer reduce volts or amps?
Voltage. A dimmer usaly chops the sine wave, leting it pass after a while.Another answerThe dimmer effectively becomes another device in the circuit. It effectively becomes a series circuit, therefore the voltage to the dimmed lights will be reduced in proportion with the relative position of the dimmer switch. HOWEVER...there is such a thing as "pulse width modulation" dimmers. They are typically used for devices that need full voltage but but you need to reduce output... such as fluorescent lights some fans and many other motors.Most dimmers are resistance type dimmers since the pulse width modulation dimmers are far more expensive.
Can you reduce the speed of a fan motor with a dimmer switch?
no you can not
Does an electric can opener convert electric energy sound energy?
Not likely - any machine wastes some energy; that would reduce the useful output energy.
Why do you now use energy saving light bulbs?
reduce electric bills without turning off too many lights
Can a dimmer switch help reduce the use of energy in a home?
No. this is because a dimmer switch increases resistance to produce less light. in other words, the dimmer switch converts the electrical energy into other forms such as heat by increasing resistance and is thus not saving energy, but wasting it.
Do dimmer switches reduce bulb life?
Answer Actually dimmer switches extend the life of a light bulb, especially if you dim them often.
Which behavior can reduce pollution that occurs due to the burning of coal?
Use ceiling fans and reduce air conditioning use in summer.
Ways to Reduce an Electric Bill?
There are some obvious ways that a person can reduce an electric bill in a given month, such as remembering to shut off the lights every time a person leaves the house. However, there are also some ways to lower an electric bill that are not so obvious. A person may be able to lower an electric bill by shutting the blinds in one's home. This can be a truly great way for any person to reduce the usage of air conditioning in a home. Overall, these are some of the best ways that a person can easily reduce an electric bill.
How do you reduce the rpm of a hydraulic motor?
Reduce the output flow of the pump supplying fluid to the motor
Could global dimming reduce the effects of global warming?
Yes, as light pollution radiates the earth's atmosphere with carbon. No one knows exactly how well will it work if EVERYONE turned off their lights, but maybe we can dim our A/C output a bit after a month of dimming lights :D
How does the negative feedbacks system work?
Some of the output is fed back to the input in such a way as to reduce change in the output.
