Hash board parts introduction

The article mainly introduces the various components needed by the hash board and their functions on the hash board.

1. Resistance

Code: R

Function: current limiting, partial pressure

Unit: Ohm (ohm or Ω)

Conversion: 1M=103K=106ohm

Law: The equivalent composite resistance value obtained after the resistors are connected in series is R=R1+R2;

The equivalent composite resistance value obtained after the resistors are connected in parallel is R=R1R2/(R1+R2);

Network resistor: Series network resistor RN, 8pinA type butt type;

Parallel network Resistor RP, 10pinB network type.

Resistance
