a meter uses its own supply to measure resistance. you dont have to remove the resistor from the circuit but you must isolate it from the circuit supply to get an accurate reading.

How do you change the blower motor resistor in a 2001 Chevy prism?

Remove the glove compartment. Its behind it just to the left of the Blower. Disconnect the connector with four wires on the bottom. Remove two hex head screws, also from the bottom. I used a 7/32 socket to remove them. Remove resister. The resister looks like a small circuit board with printed circuit traces on it. Install new resister in reverse order.


When the resistor removed from a parallel connection of the circuit whether the resistance increase or decrease?

if we remove a resistor from the parallel connection the effective resistance value will be increased.

How do you calculate thevenis resistance in thevenis ckt?

First,remove all current and voltage sources ie replace voltage source with a short and keep current source open.Now draw the equivalent resistance-only circuit and find the equivalent resistance as viewed from the terminals of the circuit.


When checking resistance does the power have to be off?

Short answer: yes. Most modern multimeters will not be damaged by external power when measuring resistance. But they will give erroneous readings. It is best to remove the power and disconnect the measured resistance from the larger circuit. A multimeter determines resistance by applying a small voltage, and measuring the resulting current. If the resistor has an external voltage source, then it will interfere with the measurement. Furthermore, if the resistance is connected to a larger circuit, then the resistance of this larger circuit will also be involved.


When determining the thevenin equivalent circuit Resistance?

To determine the Thevenin equivalent resistance (Rth) of a circuit, first, you need to remove the load resistor from the circuit. Next, you can deactivate all independent sources: replace voltage sources with short circuits and current sources with open circuits. Finally, calculate the equivalent resistance seen from the terminals where the load was connected, which may involve combining resistances in series and parallel as necessary. This value represents the Thevenin resistance of the circuit.


What is common to both thevenin and norton theorem?

To solve any D.C. circuit by using Thevenin Theorem,First of all load resistance RL is disconnected from the circuit and open circuit voltage across the circuit is calculated (known as Thevenin equivalent voltage)Secondly, the battery is removed by leaving behind its internal resistance. Now we calculate equivqlent resistance of the circuit ( called Thevenin equivalent resistance).Now we connect Thevenin Voltage in series with Equivalent resistance of the circuit and now connect load resistance across this circuit to calculate current flowing through the load resistance.Whereas in the case of using Norton theorem, we again remove the load resistance if any, and then short circuit these open terminals and calculate short circuit current Isc.Second step is same as in Thevenin theorem i.e. remove all sources of emf by replacing their internal resistances and calculate equivqalent resistance of the circuit.Lastly, join short circuit current source in parallel with equivalent resistance of the circuit. Now, we can calculate votage across the resistance which was connected in parallel with Isc.So, by knowing the open circuit voltage, we can calculate current flowing the resistance and on the other hand , by knowing the short curcuit current , we can calculate voltage across the resistance.


Where is the blower resistor located on this vehicle?

There is an upper footwell panel on the front passenger side of the car. Remove the trim panel. This exposes the blower motor assembly. Find the electrical plug on the unit and unplug it. This will expose the resister screw and by removing the screw, you will be able to remove the resister for the blower. If the resister does not show continuity when tested with an ohm meter the resister needs to be replaced. If the resister shows continuity the problem may be the blower motor relay. Hope this helps on your 1998 Mystique.

How do you change a blower resister on a 2000 Chrysler Sebring JXI?

Behind the glovebox there is one panel to remove, then use a small socket to remove the two screws holding in the fan resister card and connector. You will need to lay on your back to do this using a light source.
