What does the resistance 01a.01b.01c stand for?

The resistance value of 0 1A should be100 ⅹ1=100Ω; 0 1B indicates that the resistance value should be100x10 =1000ω (i.e.1kω); 0 1C indicates that the resistance value should be 00x100 =10000Ω (i.e.10kΩ).

This is the letter representation on the patch resistor. The code 0 1 is 100 according to the lookup table, and the code letter A is the zeroth power of 10 according to the lookup table (i.e. 1).

The 5% series patch resistance is represented by three characters: the first two digits of this representation represent the significant digit of the resistance value, and the third digit represents the digit "0" to be added after the significant digit. When the resistance is less than10Ω, R is used to indicate the position of the decimal point of the resistance in the code, which is usually used in series resistors with a resistance error of 5%.

Extended data

The resistance of a conductor is usually represented by the letter R, and the unit of resistance is ohm, abbreviated as ohm. The symbols are Ω (Greek letter, pronounced Omega), 1 Ω =1v/a, and the larger units are kiloohms (kω) and megaohms (mω) (trillion = million, that is,1million).

K Ω (kiloohms) and M Ω (megaohms), their conversion relationship is: two resistors in parallel can also be expressed as

1tω= 1000gω； 1gω= 1000mω； 1mω= 1000kω； 1kω= 1000ω (i.e. the rate of 1000).

The resistance value of resistance elements is generally related to temperature, conductor length, cross-sectional area and material. The resistance of most (metals) increases with the increase of temperature, but some semiconductors, such as glass and carbon, are the opposite. At a certain temperature, there is a formula R=ρl/s, where ρ is the resistivity, L is the length of the material in m, and S is the area in square meters.
