It is a picture of a printed circuit board, or Here’s a Nernst equation example for electrochemical systems designers. Another purpose of resistors is their way of generating heat. One such technique, surface-mount technology (SMT), allows components to be mounted directly to the surface of a board (think of them as “hitting the deck”). If you add a resistor in series with a circuit – the current in the circuit will be lower than without the resistor. This saves space but often these resistors don’t have the precision that a packaged resistor will have. Printed Resistors: Resistor material can also be printed directly onto the circuit board negating the need for soldering physical resistors on the board. 2019-05-29 A brochure of high performance chip resistors has been posted.
