ρ = R A/l.

2 or even more resistors are stated to be in attached in collection mix, if exact same existing go through each of them, when some possible distinction is used throughout the mix.

if R_s is the resistance matching to the collection mix.

R_s = R_1+ R_2 + R_3 + … Parallel mix of resistors:-.

2 or even more resistors are claimed to be in attached in identical mix, if very same possible distinction is used throughout each of them.

It is signified by E.

Kirchhoff’s regulations:-.

This Physics video clip tutorial in HINDI is clarifying the basics of shade code for 4 colour bands in a carbon resistor. A carbon resistor has 4 bands A, B, C as well as D of various colours. The very first 2 bands An as well as B show the initial 2 considerable numbers of resistance. The 3rd band C shows the decimal multiplier. The 4th band D suggests the resistance of the resistor.
