Class DCF Y1, Y2, X1. The change per volt of applied voltage is called voltage coefficient, VC, and is expressed in %/V or better, μV/V. MELF Resistor vs. CHIP Resistor --- 4-terminal Current Sense Resistor Application In order to measure current in an electrical circuit, we would let the current pass a low-resistance resistor, measure the voltage drop (named V) across both ends of the resistor with an IC, and apply Ohm’s Law I = V/R to calculate the passing current I. If we apply a voltage on a resistor it’s resistance will drop slightly in certain types. SQ cement resistors. ... SMF power metal film chip resistors.
