A trimmer resistor usually called a trim pot is a small variable resistor it is used in circuits to do preset it is trimmed with a trimmer screwdriver it is made up with a round fiber disc with a layer of carbon with a wiper that run on the carbon layer to change the resistance it always have 3 connecting pins where the center one is connected to the wiper and the other two to opposite ends of the carbon strip.

You can find the current by using an ammeter. The cheapest way (although more invasive) is to use a probe type ammeter or multimeter. To use, you need to insert the meter in the current path of the resistor (in series with the resistor). These meters are fairly cheap - as low as $8 if you shop around. If it is not feasible to break the circuit and insert the meter, and you have room around a wire going to the resistor, you could use a clamp on ammeter as well. These are typically more expensive.

If you understand resistor codes, you can also use a volt meter/multimeter to measure the voltage drop across the resistor (put the probe in parallel with the resistor). The current should be equivalent to I = V / R.

If you don't know resistor codes, do an online search to match colors with numbers. There should be three stripes. The first two are the resistance and the third is a magnitude. For example, if the first color matches the number 1, and the second matches 8, and the third matches 3, then this is a 18 x 1000 = 1.8k ohm resistor.

where else it would go through.....

the current entering the first resistor must pass through the next preceding resistors in order to reach the positive/+ve potential so as to complete the circuit.

Current flow is the actual flow of electrons so it goes from the ground (negative most point) to th emost positive point. lectrons are a negatve charged unit so they travel towards the positive point.

It is used to dial in a specific resistance within the range of the box. It can be used wherever you need a resistor of an unknown value or a precise value. Most decade boxes provide reistance with .01% of the desired resistance. I've used them to balance a wheatstone bridge that had a tiny mV offset.

V = IR

= 8x10-3 (8 mA) * 10x103 (10k)

= 80v

By Ohm's Law, current is voltage divided by resistance, so if you double both the voltage and the resistance, the current would remain the same.

Of course. Additional resistors change total resistance, which changes current, which affects power.

When resistors are connected in series in a circuit . the voltage drop across each resistor will be equal to its resistance, as V=IR, V is direct proportional to R.

An

A: The relationship is that the current will divide for each paths in a parallel circuit and the voltage drop across each will be the source voltage.

In a series circuit the current will remain the same for each component but the voltage will divide to reflect each different component value. And the sum of all of the voltage drops will add to the voltage source

the resistance of a diode is .4 ohms is made of tantalum or .7 ohms if made of silicon.

ANSWER: THE RESISTANCE OF A DIODE IS SIMPLY V/I the impedance however is defines by Boltzmann constant

does the lock on the passenger door still work? if nothing from either door then check every fuse on the car. if all fuses are good then check the power door lock relay in the right front kick panel. if not that then remove door panel and check if the motor will work with direct current to the lock.

A: In a series circuit the current remains the same for each components only the voltage across each component will change and only if the components are of different value.

The VIN is on a metal plate on top of the dash ( look through the windshield

from OUTSIDE on the drivers side ) and also , open the drivers door and it is

EGR problem

just removed mine it is hiden behind the emegency brake pedel you must remove the left f tire then remove the wheel well liner at least the rear of the liner pull the liner forward the ecm is in the firewall 2 /11 mm nuts hold it in place one 10 mm bolt holds the conector also you can see it from under the hood far left side to the left of the main wiring conctor

Power is equal to voltage times current (P=V*I) in Watts, and from Ohm's Law, the voltage across a capacitor is equal to the current passing through it times the resistance (V=I*R). The power is then P=I2R. For a current of 5mA and a resistance of 8.2kOhms, (5*10-3A)2*(8.2*103Ohms) = 0.205 W.

Not necessarily, but continued driving may lead you there if it isn't fixed. It may be in the transmission control system that is causing the ill behavior. Pukenstein@aol.com

If you don't smell gas or see any gas leaking :

push the reset button down that has popped up on the top of the switch ( the fuel pump inertia / shut off switch is in the front passenger footwell by or behind the kick panel )

turn the ignition key to the RUN position for a few seconds and then turn the ignition key to the OFF position

make another check for any gas leaking or the smell of gas , if none , go ahead and start the engine

If you look on the cover to the fuses, or in your owner manual, it tells you what each fuse is for.
