Resistance?

something that forces the electrical modern now not to flow is called the resistance.

How to Calculate Resistance?

Following are the same old voltage present day resistance formulas to measure resistance:

Colour Codes:

color codes correspond to the rankings that outline the capability of positive electric additives. but we have considered the codes for resistances only.

  • Hold the resistance on your hand with tolerance bands to the most proper
  • start noticing bands one by one from left to right and choose a value from the desk (in opposition to coloration) to estimate the desired ohm value.

Serial Resistance:

\(R_{total} = R_{1}+R_{2}+R_{3}+R_{4}+R_{5}+...+R_{n}\)

Parallel Resistance:

\(R_{total} = \dfrac{1}{\dfrac{1}{R_{1}}+\dfrac{1}{R_{2}}+\dfrac{1}{R_{3}}+\dfrac{1}{R_{4}}+\dfrac{1}{R_{5}}+...+\dfrac{1}{R_{n}}}\)

Conductor Resistance:

\(R = \dfrac{L}{A*C}\)

Where;

L = duration of Conductor

A = pass Sectional region of the Conductor

C = cloth’s Conductivity
