They also have much lower noise levels, on the level of 10–100 times less than thick film resistors. [8] Thick film resistors may use the same conductive ceramics, but they are mixed with sintered (powdered) glass and a carrier liquid so that the composite can be screen-printed. This composite of glass and conductive ceramic (cermet) material ...
For example, a 10 ohm resistor connected in parallel with a 5 ohm resistor and a 15 ohm resistor produces 1 / 1/10 + 1/5 + 1/15 ohms of resistance, or 30 / 11 = 2.727 ohms. A resistor network that is a combination of parallel and series connections can be broken up into smaller parts that are either one or the other.
While discrete resistors in the range of few tens of megohm are very common, making giga-ohm range resistors is more complicated. Discrete resistors are available up to several tera-ohms, but are expensive because of limited demand. Sometimes, a combination of active and passive electronic devices is used to achieve such a high resistance. [1]
If a manufacturer sold resistors with all values in a range of 1 ohm to 10 megaohms, ... 100, 220, 470, 1 k, 2.2 k, 4.7 k, ... such as resistors, capacitors, ...
SMD resistors on the backside of a PCB. Pass current in proportion to voltage and oppose current. Resistor – fixed value Power resistor – larger to safely dissipate heat generated; SIP or DIP resistor network – array of resistors in one package; Variable resistor Rheostat – two-terminal variable resistor (often for high power)
