WebResistance is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω). Ohms are named after Georg Simon Ohm (1784-1854), a German physicist who studied the relationship between voltage, current and resistance. He is credited for formulating Ohm's Law. WebDec 3, 2024 · Scratch the lead on the plate to ensure it's in contact. Touch the meter's black lead to the metal coil housing and watch the meter. If the meter's display indicates a value of 2.5 to 5 K ohms, then the coil is good. If, on the other hand, the meter display shows a "1" or infinity sign, or the display needle jumps to the far right of the scale ... WebOhm’s Law. Ohm’s law states that for some devices there is a relationship between electric potential difference, current, and resistance. The equation is: I =\dfrac {\Delta V} {R} I = RΔV. Where I I is current, \Delta V ΔV is electric potential difference, and R R is resistance. harlow council service charge
