Resistors are electronic segments. They are shading coded with stripes to uncover their resistance esteem measured in ohms and additionally their assembling resilience. There are two sorts of shading codes, four band and five band. To begin with, the four band. Discover the resilience band, commonly it will be gold. Beginning from the flip side, distinguish the first band ,record the number connected with that shading; for this situation accept the shading is Blue, in this way the number is 6. here accept it is red, so record a "2" beside the six. Presently read the third or "multiplier" band and record that number of zeros. In the event that the "multiplier" band is Black don't record any zeros. On the off chance that the "multiplier" band is Gold move the decimal point one to one side.
In the event that the resistor has one more band past the resilience band it is a quality band. Perused the number as the '% Failure rate per 1000 hour'. This is evaluated accepting full wattage being connected to the resistors.
1% resistors have three groups to peruse digits to one side of the multiplier. They have an alternate temperature coefficient keeping in mind the end goal to give the 1% resilience. Should you experience a resistor and don't have a clue about the shading codes, utilize this edge page above to decide its resistance esteem.
You can measure it with a meter or calculate it by using Ohm's Law. Ohm's Law has four variables and with only two input variables you can calculate the remaining one or even two unknown variables.
Watts or Power=P; Volts or Electricity=E;
Amperes or Current=I; Ohms or Resistance=R. (Below are formulas for R):
R=Ohms can be calculated by (E divided by I); (E2 divided by P) or,
(P divided by I2). (See Ohm's Law formulas to calculate remaining three variables: P; E; or I).

What resistance must be connected in parallel to 6.0-ohm resistor to reduce the combined resistance to 15-ohm?
No such resistor exists. Any resistor placed in parallel with a 6.0 ohm resistor is going to reduce the combined resistance below 6.0 ohms.
What is a contact resistor?
A: I snot a resistor but rather an unwanted resistance on a contact
What does r mean in a resistor?
R stands for the resistance.
When a 1 ohm resistor and a 1 ohm resistor are connected in series what is their conbined resistance?
The combined resistance will be 2 Ohms.
What component that makes it more difficult for current to flow?
IF there is a Resistor
Describe the purpose of the coloured bands on a resistor?
The colored bands on a resistor indicate its resistance value and tolerance. By interpreting the color code, you can determine the resistance value of the resistor and the range within which the actual resistance may vary. This helps in identifying, sorting, and using resistors in electronic circuits.
What do the colours on resistor mean?
The colored bands on a resistor represent the resistor value and tolerance. The first two bands indicate the significant digits of the resistance value, the third band represents the multiplier, and the fourth band (if present) indicates the tolerance of the resistor. By decoding these colors, you can determine the resistance value of the resistor.
What is the difference between an ohmic resistor and a non-ohmic resistor?
A non-ohmic resistor doesn't have a constant resistance. A ohmic resistor has a constant resistance.
What resistance must be connected in parallel to 6.0-ohm resistor to reduce the combined resistance to 15-ohm?
No such resistor exists. Any resistor placed in parallel with a 6.0 ohm resistor is going to reduce the combined resistance below 6.0 ohms.
What does resistor perform?
A resistor's resistance is measured in ohms. The higher the resistance the less current will flow with a constant voltage applied across the resistor. In terms of Ohm's Law Voltage = Current x Resistance.
What is voltage drop with 30 volts across 25 ohm resistor?
To tell you that we need to know the resistance of the entire circuit.
What is a contact resistor?
A: I snot a resistor but rather an unwanted resistance on a contact
What does r mean in a resistor?
R stands for the resistance.
What are the losses in resistors?
The power lost in a resistor is(the current through the resistor) times (the resistance) watts. That's the same thing as(the voltage across the resistor)/(the resistance)watts.
When a 1 ohm resistor and a 1 ohm resistor are connected in series what is their conbined resistance?
The combined resistance will be 2 Ohms.
What is the resistance of a 10-ohm resistor and a 7- ohm resistor in a series?
