Resistors and How they Work

Resistors start from Wires to Wirewound Types. Carbon Film Resistors are most Common, Metal Film Resistors are more stable and accurate. We have now SMD types with lower power some are Laser Trimmed Types for accurate values. Resistors Arrays are used in Digital Circuits.

Resistors and How they Work

1/4 W Resistors have a Voltage rating of around 200-250V. Even when using a High value like 1 Meg use two in series when it is across Mains 230 V AC. 470K + 470K - you get around a Meg at 500V
Rating.
