How to work out the resistance
WebThe first two digits indicate the resistance value—while the third digit is the multiplier. Resistor color code for 330 Ohms. For example: “482” = 48 x 100 ohms = 4.8 kiloΩ. If the resistors have values less than 100Ω, you can write it as: “480” = 48 x 10 0 (which is equivalent to 1) = 48 x 1Ω = 48Ω or 48RΩ. Web12 sep. 2024 · The resistivity of a material is a measure of how strongly a material opposes the flow of electrical current. The symbol for resistivity is the lowercase Greek letter rho, ρ, and resistivity is the reciprocal of electrical conductivity: ρ = 1 σ. The unit of resistivity in SI units is the ohm-meter (Ω ⋅ m.
