How do you know if your blower motor is bad or if you need to just change the resistor?
Use a jumper wire from the battery + (pos) terminal to the positive on the blower motor, and run a - (Ground) wire from ground on the motor, to chassis or frame.
Where is the voltage regulator on 1986 Mercury Marquis?
Shiny square box on drivers fender near headlight.
How do you replace the voltage regulator in a 1990 Mercury Sable?
Voltage regulator is located behind the battery in the inner left (driver's side) panel, in the front part. You must remove the battery in order to reach the regulator. Use a quality replacement part or your eec computer may go toast. Voltage should read aprox. 12V with engine off, and about 15V with engine running. Good luck fella.
What causes the ballast resistor on 1972 Plymouth to get hot?
the ballast resistor is designed to turn unwanted current into heat high temperatures are normal.
What precautions should be observed before using a diaphragm?
Each client will undergo a physical examination and a Pap smear. If these are normal, the physician will fit the patient for the device and give instructions on how to insert, remove, and clean the object
Where is the voltage regulator on a 1999 Ford Ranger V6 3.0L?
The voltage regulator is an integral part in the alternator assembly. So it's located inside the alternator.
No doubt either of those approaches would certainly work.
Personally, since I don't see well enough to wire a CMOS board, and I don't know
how to program a PIC, I would probably go to the big 'home improvement' store
and buy a couple of timers. One of them has to be the kind with two AC outlets ...
one normally on and one normally off.
-- If the interval you want is less than 24 hours, then all you need is a simple
kitchen timer.
If it's more than 24 hours, then you can do it like this:
-- Plug the 'double-throw' timer into the wall. Plug an ordinary kitchen timer
into its normally-off outlet.
-- Now here comes the part where you need to understand electronics and
know how to use solder and black tape: Attach two AC line cords in parallel
to whatever supply you use to power your solenoid.
-- Plug one line cord into the normally-on outlet of the first timer, and the other
line cord into the kitchen timer.
-- Set both timers so that their sum adds up to the interval you want.
While the double-throw timer is running, it powers the solenoid power supply,
and the kitchen timer is unpowered.
When the first timer expires, its two outlets flip. The kitchen timer starts running,
and it powers the solenoid supply until it too expires.
This rig can run any interval from very short to almost 48 hours.
Sometimes I'm so clever I make myself sick. Especially in the abstract.
I'll leave you to work out the kinks and the bugs and actually make it work.
That should be no problem for a guy who can work with CMOS ICs and PICs.
The dc input resistance of MOSFET is?
it depends on the type of the circuit you are analyzing..it could be a voltage divider, emitter follower, be specific on what type of circuit and maybe i can help you aobut this question.
How is a Trimmer capacitors made?
There are different kinds of trimmer capacitors, but the most common type is made from interleaved layers of metal and Mylar (or some kind of plastic) with a screw that allow the layers to be tightened together, increasing capacitance as needed. Alternate layers of metal are connected to each terminal, basically making a meshed plate capacitor, where the distance between plates is controlled by the screw.
If the bulbs and fans are designed to run on different voltages, then we'd have to know
what the rated operating voltage of each item is, and then arrange them cleverly.
If all of the bulbs and fans are 117VAC units ... each one could be individually plugged into
a household outlet ... then combining them is easy:
-- Connect one end of each bulb, one end of each fan, and one side of the electric cord
all together. Cover the blob of six wires with insulating electrical tape.
-- Connect the second end of each bulb, the second end of each fan, and the second side
of the electric cord all together. Cover this second blob of six wires with insulating tape.
-- Plug the electric cord into a standard household outlet. Each bulb and fan should
operate normally.
To regulate a powersupply. The variations of voltage will be nullified by this ic. For example a three legged ic say number 7812 gives 12v dc supply if you are applying a voltage of 13 to 24vdc at a maximum current rate of 1 ampere. If applied voltage is 24v the dissipation will be approximately 12w.
What are the ideal op-amp approximations?
Ideal op amp approximations: -no current goes into the positive or negative input of the op amp. -The open loop gain is infinite. -Voltage at positive input is the same as the negative input.
What is a conventional current?
Conventional current shows current flow from + to -
amp meters are labeled this way
(conventional current flow) (hole flow)
Physics shows that electrons are moving or flowing from - to +
(electron flow)
Tubes (deforest valves) sort of blew conventional current away
semiconductors with different doping materials confuse it more
so most new books relate to electron flow
voltmeters ammeters are labeled the same since the 18th century
How transistors are classified on the basis of power?
There are two primary types of transistors classified on the basis of power: bipolar junction transistors (BJT) and field effect transistors (FET).
Bipolar junction transistors are current-controlled devices, meaning that the amount of current flowing through the device is controlled by the voltage applied to the base electrode. The base-emitter voltage (VBE) and base-collector voltage (VBC) determine the amount of current flowing through the device. The current flowing through the device is given by the following equation:
I = β * (VBE - VBC)
Where β is the current gain of the transistor.
Field effect transistors are voltage-controlled devices, meaning that the voltage applied to the gate electrode controls the amount of current flowing through the device. The voltage applied to the gate electrode determines the width of the conducting channel between the source and drain electrodes. The current flowing through the device is given by the following equation:
I = μ * W * (VGS - VDS)
Where μ is the mobility of the carriers in the channel, W is the width of the conducting channel, VGS is the voltage applied to the gate electrode, and VDS is the voltage applied to the drain electrode.
Yes.
Why is it not good to operate a transformer above its nominal voltage?
Operation above the rated supply voltage causes the ferromagnetic core to enter saturation; this means that the primary inductance is reduced and since the primary current is limited by primary resistance +inductance then the primary current will increase and possibly cause the primary winding current capacity to be exceeded. Also the iron core hysteresis loss will likely increase and cause the core temperature to rise. We have not considered eddy currents in the core, probably these are less than the hysteresis core loss.
<><><><><><><>
Addition:
also the stresses that caused by increasing the voltage will over heat the transformer by mean the life time is redused, for example: if the life time for a transformer is 20 years this number will decrease due to operating the transformer on a higher voltages than the rated...

What is the circuit in which two switches are connected in a series?
Two switches in series would be an analogue representation of a solid-state AND logic gate.
What is the name of the process used to connect electrical components to a circuit board?
The process of connecting electrical components to a circuit board is
known as glueing, cementing, strapping, or bolting.
The process of connecting components electrically to points in the circuit is
known as soldering.
What is the lifespan of a resistor?
A resistor doesn't deteriorate with age, and has no particular 'life-span',
as long as it's used properly.
-- A resistor in a box on the shelf, or in a circuit where it stays cool, will last
indefinitely.
-- A resistor in a circuit where it's forced to dissipate enough power to make it
hot may change its resistance value permanently, but will continue to operate.
-- A resistor in a circuit where it's forced to dissipate even more than that,
to a ridiculous extreme, may melt or explode. When that happens, it's the
end of the resistor's life-span. But it wasn't the resistor's fault.
