What is the colour of 2k ohms 2 percent tolerance resistor?
red 2, black 0, red 102, red 2%. 20 x 102 with 2% tol.
What is the value of current in a series when one resistor is open?
Since it is a series circuit with only one path for current, an open anywhere along that single path will cause current flow to be 0 amps.
A resistor is marked with the following color bands brown black red and silver. What is the resistance of this resistor A. 10 B. 10000 C. 100 D. 1000?
The color bands on the resistor indicate its resistance value: brown (1), black (0), and red (multiplier of 100). This means the resistance is 10 multiplied by 100, which equals 1000 ohms. Therefore, the correct answer is D. 1000.
What are the values of armature and field rheostat to be maintained during starting of a d.c motor?
you want full field while starting 0 Ohms and maximum series on armature then bring the armature resistance to zero as it approaches running speed its a good idea to run with armature at 0 ohms armature will use the same amount of power as the resistor If you want to run at more than base speed you can now weaken the field
How do you identify carbon resistor using colour code?
To identify the value of a carbon resistor using colour code use the following table...0 - Black1 - Brown2 - Red3 - Orange4 - Yellow5 - Green6 - Blue7 - Violet8 - Grey9 - White... and look at the bands. The first two bands will be the digits, and the third band will be the multiplier. For instance, Brown - Red - Orange will be 12000 ohms, where the 1 is the first band, the 2 is the second band, and the three 0's is the third band.If the third band is Gold or Silver, then the multiplier is 0.1 or 0.01 respectively. For instance, Brown - Red - Gold would be 1.2 ohms, and Brown - Red- Silver would be 0.12 ohms.If there is no fourth band, the resistor is +/- 20%. If the fourth band is Silver, the resistor is +/- 10% and, for Gold, +/- 5%.Some high end resistors have more bands. The 1% resistor will have a third digit band, and some resistors will have a band indicating temperature coefficient.
How to know if the resistor is open and shorted?
I assume that the person asking the question meant "open OR shorted" as these are opposite terms. Most resistors will open when they are damaged. It is very rare to find one that is shorted. To determine if the resistor is open or shorted simply use a multimeter set to measure ohms. Place the leads across the resistor and it should read the resistance value of the resistor. If it measures max range of the meter (some digitals will display "OL") then the resistor is open. If it measures 0 or very close then it is shorted, which as mentioned above, is unlikely.
Why are resistances parallel to short circuits neglected in a circuit?
You can consider a short circuit to be a resistor with R=0 Ohms. It is then clear by the equation for calculation of parallel resistance that the combined resistance of a resistor in parallel to a short circuit is 0. Consider the following example with R1= 1k Ohms and R2= 0 Ohms: Rtotal = R1*R2 / (R1+R2) = R1*0 / R1 = 0 Ohms.
What does 0 ohms indicate?
0 ohms on your ohm meter indicates an open circuit; no resistance to the flow of electricity.
What is the value resistor brown black orange?
Brown (1) - black (0) - orange (4 more 0's) - 10,000 ohms.
A resistor is marked with the following color bands brown black red and gold What is the resistance of this resistor?
1000 ohms = 1Kohm; silver is the tolerance band of the resistor. Silver signifies plus or minus 10%. The fourth band is always the tolerance band. If there is no tolerance band, the tolerance is plus or minus 20%. A gold band would signify plus or minus 5%.
What value multiplier resistor is required to create a 0-100V range voltmeter from a 10mA meter movement if the meters coil resistance is 50ohms?
10 ma times 50 ohms is 0.5 volts. 0.5 volts is one two hundreth of 100 volts, so the multiplier resistor on 200 time 50, or 10,000 ohms.
What is the colour of 2k ohms 2 percent tolerance resistor?
red 2, black 0, red 102, red 2%. 20 x 102 with 2% tol.
Does zero amps indicate continuity across the length of a wire?
Ohms not current (amps) indicate continuity. If you have no continuity then you will read an open line condition (OL on meters). If you have continuity you will have some type of resistance reading in ohms. 0 ohms would indicate continuity 0 amps indicates no current flow.
What is the value of current in a series when one resistor is open?
Since it is a series circuit with only one path for current, an open anywhere along that single path will cause current flow to be 0 amps.

How do you converts ohms to dB?
You must find a resistance value for 0 dB as reference. If 1 Ohm = 0 dB then 10 ohms = 20 dB and 100 ohms = 40 dB.
