What is the unit of measure for resistance?
Answer (3)
ohms ;
The unit of measure for resistance is the ohm, symbolized by the Greek letter Ω (omega).
Resistance is a fundamental concept in the field of electricity and electronics, which falls under the broader subject of Physics. It describes how much a material opposes the flow of electric current. The higher the resistance, the harder it is for the current to pass through.
The ohm is an established unit of measurement within the International System of Units (SI), which is used worldwide to ensure consistency in scientific measurements. This unit is named after Georg Simon Ohm, a German physicist who studied the relationship between voltage, current, and resistance in the 1820s. His work led to the formulation of Ohm's law, which can be expressed as:
V = I × R
Where:
V is the voltage across the component in volts ( V )
I is the current through the component in amperes ( A )
R is the resistance of the component in ohms ( Ω )
Understanding resistance and its measurement is crucial for analyzing and designing electrical circuits, which is a key part of technology and engineering studies.
