Resistance in an electrical circuit is measured in which unit?

Resistance in an electrical circuit is measured in ohms, which is represented by the symbol Ω. The concept of resistance refers to the opposition that a substance offers to the flow of electric current. A higher resistance value means that it is more difficult for current to flow through the material.

Understanding resistance is crucial for a variety of applications in electronics and electrical engineering, as it helps in designing circuits that control the flow of electricity effectively. Ohm's Law, which relates voltage (in volts), current (in amperes), and resistance (in ohms), further emphasizes the significance of this unit in the context of electrical circuits. By knowing the resistance, one can determine how much current will flow when a particular voltage is applied.
