What is the effect of connecting 4 1 ohm resistors in series to the power line? [Copy link]

What is the role of connecting 4 1 ohm resistors in parallel in a circuit of a board designed by a supplier before?

Without an electrical schematic, it's impossible to say what it does.

The reason why four resistors are connected in parallel is probably because we can't find a 0.25 ohm resistor with a larger power dissipation.

Dividing current and increasing power consumption

The purpose of using resistors in parallel is to increase resistance, increase power dissipation without changing the package, and save costs under specific conditions.

The main purpose is to increase power and expand the heat dissipation area, and of course the temperature will also be reduced.

At the same time, since the accuracy of a single sensor has a certain degree of discreteness, the four sensors in parallel can be considered to be discretely complementary, and the accuracy is slightly improved.
