What is the answer to the light bulb Riddle?
Here it is: If the light is on, then switch number 2 controls it. If the light is off, then go and feel the bulb with your hand. If the bulb is hot, then switch number 1 controls it, and if the bulb is cold, then switch number 3, the one you did not touch, controls it.
Can you have 3 light switches one light?
A light or lights can be controlled by more than one switch. The usual practice in home construction is to use 3-way switches. “3-way” is the electrician’s designation for a single pole double throw (SPDT) switch. The switches must create a complete circuit for current to flow and the bulb to light.
How many light bulbs are turned on at the end?
Let’s realize what we discovered. If there’s no randomness, then we’ll get 10 light bulb that are turned on in the end. If there’s a 50–50 chance to press the switch, then we’ll get 50 light bulbs that are turned on.

Do LED bulbs get hot?
Yes, new technology LED lighting can and will get hot, but when compared to the lighting of the past, temperatures are much safer.

What’s the purpose of a 3-way switch?
A 3-way switch is one that allows you to control a ceiling light (or other electrical fixture) from two separate locations. Common scenarios would be 3-way switches located at both the top and bottom of a stairway, or having 3-way switches next to doors in a room with two entry points.
Can you replace a 4 way switch with a 3-way switch?
Yes, and no. If the circuit has a four-way switch it needs two three-way switches in order to work properly. Three-way switches allow you to control one or more lights from two locations. If you need to control the light(s) from more than two locations, you install a four way switch in between the two three-ways.
Is it cheaper to leave LED lights on?
LED, or light emitting diode, bulbs are not affected at all by being turned on and off. This characteristic makes LED bulbs a top energy savings lighting choice. They’re a great option, Energy.gov says, when used with sensors that rely on on-off operation. They also turn on at full brightness almost instantly.
How much does it cost to leave a light on all night?
A “normal” incandescent bulb costs about 0.75cents per hour, and LEDs or CFLs cost only one-sixth of that – so leaving the lights on (either overnight or while you’re at work for the day, say both are about 8 hours) costs you roughly 6 cents for a normal light and a bit over 1 cent for modern bulbs.
What is the 3 7 chicken?
CHICKEN:it is seven lettered word.so,we will extract the letters out of it as per the given fraction,i.e. 3/7. The letters thus exracted are first 3 letters of the word,which are CHIC. CAT:this is a three lettered word.So,we will extract first two letters from it(as per the given fraction,that is 2/3).
