11 Ιουλ 2021 · Resistance (also known as ohmic resistance or electrical resistance) 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). The larger resistance, the greater the barrier against the flow of current.
