**Find The value of Burnt Resistor by Three Simple Methods
**

We can find the Values of **burnt resistors** by these three handy methods below.

**Method 1 **

- Scarp the outer coating.
- Clean the Burnt Section of the resistor.
- Measure resistance from one end of the resistor to the damaged section.
- Again measure the resistance from damaged section to the other end of the resistor.
- Add these two value f resistances.
- This is the approximate value of Burnt resistor.
- Just add a small value of resistance for damaged section i.e., suppose the value of burnt resistor was 1k Ω, but you got 970 Ω. So just add 30 Ω, and you will have 1k Ω.

**Method 2**

This method can also be used for finding the value of burnt resistor(s) (also, may be applied on connected resistors in the circuit) in case if you don’t know about Resistance Color Coding.

- Connect Resistor to Multimeter and measure voltage drop across the burnt Resistor.
- Now measure the current flowing into the resistor.
- Multiply both values and you will get the wattage of Resistor (As P = VI i.e. Ohm’s law).
- This Wattage must be less than the wattage of the resistor being replaced.

**Method 3**

This method could be used better if you know the expected Output Voltage of the circuit and you have a set of resistors of the same wattage as burnt resistor. Perform this method if you don’t know the value of resistor.

- Start with a high value of resistance and temporarily connect this resistor instead of burnt resistor.
- Measure the expected output voltage of the circuit. If you obtained same voltage as expected voltage then you have done.
- If you don’t know about the expected voltage, then keep reducing the value of resistor until you satisfy with the work of circuit for which purpose it was designed for.

Thats the easy way to explain realy good

nice explanation.done well

please i need to know about electrical

A non centre tap transformer outputs 23v dc.

How do I find the amp output.

Thanks

How do i find the resistance value of a burnt redistor?

My odds has been interestingly relieved thro’ this…”tnapeq”

It’s very good and we can use in various places.such as VID.

I have a new idea, good resistor series connect with the burnt resistor and then mesure the resistor value notify then mines(-) the good resistance value from notified value due to the remaining value is that
