It means it could shock you to death. Painful

Breadboard

Alternating current. Direct current is used in batteries.

The circuits are simply called microchips,because these circuits are too small to be seen clearly with a naked eye.

Yes, but only for balanced loads (current in all three phases the same value). The voltage value used is the phase to phase voltage.

The low state dc noise margin for TTL dates is 0.3v and the high state noise margin is 0.7v

The voltage for anything should match the supply voltage.

The arrow always points to the negative lead.

Otis f.boykin made and invented first the resistor

Everything will flow backwards

Remove the glove box, Remove the lower trim panel from the facia above the passenger side footwell and the lower trim panel from the centre of the facia.

Release the retaining clip and remove the passenger side front footwell air duct.

Disconnect the wiring connector from the fan motor, noting the correct routing of the wiring.

Working your way around the fan motor air distribution housing, undo the retaining screws, then unclip the motor from the housing

Remove the fan motor

From inside the car, reach up behind the air disribution housing, and disconnect the wiring connector from the underside of the blower resistor which is on the left hand side of the air distribution housing, unclip the resistor from the air distribution housing.

In order to determine this, it will be necessary to find which resistor 'maxes out' at the lowest voltage. This can be found using the equation Vi=sqrt (Pi*Ri) for each resistor, where Pi is the power rating of resistor i and Ri is the value of resistor i. Once this is found, the power dissipation of each other resistor can be found using the equation Pi=(Vl^2)/Ri, where Vl is the voltage that maxes out the resistor which maxes out at the lowest voltage, and Ri is the resistance of each resistor. The equivalent power rating would then be the sum of the power dissipated across each resistor.

By the rating of the overcurrent device.

The ammeter is reading zero because there is no current flowing. This is because one of the resistors is faulty; the faulty resistor has an "open circuit" (open circuit means there is a broken connection). We know that: Ohms law is: V = I x R (voltage = current x resistance) Therefore because there is zero current in each resistor there will be zero voltage across each resistor. However we also know that: Kirchhoff's voltage law is: V1 +V2 +V3 + … = Vs (the sum of the voltage drops accross each component in a circuit MUST equal the supply (or battery) voltage). But if all the resistors are zero volts, then what component equals the supply (or battery) voltage? The battery voltage is developed across the open circuit… therefore the resistor which is faulty will have a voltage across it equal to the battery voltage. That easy to measure with a volt meter! hope this helps

he purpose of EOLR's is to allow the control panel to supervise the field wiring for open or short circuit conditions. How the alarm responds to each depends on the panel as well as system zone programming, but generally speaking, an alarm views an open circuit as a fault or alarm condition, and a short circuit as a trouble or alarm condition (if armed). The purpose of EOLR's is to allow the panel to differentiate between the two conditions by looking for a known resistance.

EOLR's should be installed at the last device on the loop, electrically speaking, and not inside the control, unless special conditions are met. The benefits of EOLR's on protective zones with all concealed wiring is commonly argued by professional installers, as well as EOLR's installed inside the control unit, negating their effetiveness, as well as disabling the EOLR feature and using NC (normally closed) loops for zone definitions. The use of EOLR's is recommended and is particularly important when the field wiring is subject to damage or compromise.

A fire EOLR should always be installed at the last device and never inside the control or across the zone defined as fire, as this is an inherent safety issue.

Some equipment supports Double End of Line Resistors (DEOLR) to further differentiate between conditions that may exist on the loop.

Flow of current decreases proportionately.

Mosfets should be protected from static electricity. Handle with anti static protection. Use solder-wicks when desoldering as solder-suckers create enough static electricity to damage mosfets.

Also susceptible to over voltage. A mosfet will break if a short cuircuit happens thru it and blow other paralleled mosfets too.

in the real world

FET is a field effect transistor, abbreviated to FET. There are two basic types of FET: a junction FET abbreviated to JFET and an insulated gate FET , abbreviated to IGFET. The most common type of IGFET is a metal-oxide silicon FET, Known as a MOSFET. Modern microprocessors may contain tens of millions of MOSFETs.

In case of open circuit test of transformers we measure iron losses and hence the power lost here is being measured by the wattmeter.

Generally, in electrical circuits it is desired to turn on/off an electrical device depending upon the value of input signals.To implement this action different type of logic gates are used.So, depending upon the given combination of inputs, the gate either turns on/off the electrical devices.

Hi, I am tracking down the owners manual now to find out, my guess is it is no different that changing the wires on a table saw motor...will check back.
