What's a C1 capacitor in a circuit board for a toaster?
Hi Ismael ,what's goin on. How are you ? Hope well .
So ...... I have some info for you to your Q. .
I think the most important part or the key point to know is understanding the Capicitor , capacitive circuits , and what the numbers mean .
Well I have my Master in Electricty and is the only job I've ever had for well over 30 years and I have over the years rewritten many electrical apparatus , parts , or components , definitions and functions for easy understanding to others . In my college texts in the electrical industries , (there are very many ) I find them really complex to understand for ones who simply just want a basic knowledge of comprehensive elementary use of . So here is some of the parts of term papers I wrote about in school and hope they help
THE CAPACITOR .
THIS component used in a circuit is for the simple ability to store higher or more volt /amps , the than the volts applied and to discharge it's total amount in or at a specific time or when triggered by another device when called for.
The capacitors work is to apply a ELECTROMOTIVE FORCE or
EMF (volts ) of a higher voltage that is 600 % more than applied volts to start a component than the applied voltage can do but takes longer thus creating heat and eventually failure
Once the capacitor sudden disharge or release of all its enrgy,
they recharge themselves with same circuit as the applied voltages or a portion of that voltage from another circuit in time.
Much like a car battery , only a battery is not to disharge it's power all at once.
In a nutshell hungh . You should read the electrical mathematicians vol. 3 edition ....whew ...
ok so like here is your applied example on the above , and then we will get to the toaster.
Im going to use a window air conditioner as a very simple example:
when you plug the a/c in the applied voltage is 110 v. In this circuit
it maintains a 110 volts throughout the unit and in and out the controls , the devices or components to continue circuits to function and work or run . The motor is the biggest power consumer. When it is off or at a stand still ( the shaft is not rotating and the rotor (shaft ) is at a dead stop ) a huge amount of power
will have to be used to even just get it to move, let alone rotate 1 time . So ahead of this we use a capacitor to jump start that rotor
to wake it up, get it to rolling or rotate .once it has got the momentum going the Applied 120!volts takes over and then full speed is obtained and maintained for the out put of that rotor to perform work . In the meantime the capacitor is being charged for the next start up .This process is quick and most times instantaneous. For some math to show what it would take to start the rotor to even turn with the applied volts
v/a x 600%
e x I = ? 120 x600 = 3600 volts
Thats a lot of power . Keep in mind though it can reach3600 v
but so fast it begins to drop before it even starts ,,,instantaneous.
Now For the numbers on the boards they are a reference to as there are more capacitors in this board and it is to denote the location on the board , what it controls and capacitors size in a separate printed schematic As in Capacitor #1 or C1 . In a schematic it will show like this
C1- .03 micro farrad capacitor . For R2 (relay # 2 ) to M1(motor on air cond.
then in order
C2 - .08 ? ( ? is close to the correct symbol used to represent micro farrad ) and .o8 is the amount or size of Cap.
1 farrad is HUGE .. 1 FARRAD WOULD EQUIVALENT THE SIZE OF A THREE STORY HOUSE,WITH 12 BEDROOMS .
Notice the value in my example....MICRO BUT .08 .......8 hundredths to the micro .08 x 000,000,001 negative it's rather small now ....HUHUHHAHA . Well there you go and this my freind
is as simple as it will ever get.
When I was going through my journymans years we had a warehouse full of electrical parts . And thousands of different sizes of Caps. So Huhuhaha , what we would do is take an old extension cord , expose the wires and strip only the very ends of the two wires , plug the other end in to the wall receptacle and charge a capacitor about the size of a deck of cards or two decks of cards , and when a apprentice or a grunt walks close by , I would toss the charged capacitor his way and say HEADS UP !
Well his first reaction is to catch the dang thing and POW .
He drops it as fast if not faster than he caught it . Huhuhaha
remember That 600. %. or 3600 volts , we discussed well there ya go ..... They will catch it every single time ........it's harmless in this state ,BUT it's a shocking experience.!!! Let me if this helps for your toaster , in identifying what C1 goes to . Hint : probably the elements that heat up red and heat up quick .
Get back with me when you get a chance . After all a it only becomes an answer after a solution is given
Adios ,,,,A. Goodwin
