Word
ohm
US/ˈoʊm/
UK/ˈəʊəm/
Definition
n. the standard unit used to measure how much a material resists the flow of electricity. A higher number means it is harder for the current to pass through.
n. the SI unit of electrical resistance, equal to the resistance of a circuit in which a potential difference of one volt produces a current of one ampere. Named after the German physicist Georg Simon Ohm.
Examples
“The speaker has an impedance of eight ohms.”
“To protect the LED from burning out, the engineer added a ten-ohm resistor to the circuit.”
“The precision of the measurement was critical, as even a fraction of an ohm could significantly alter the performance of the high-frequency transmitter.”

Usage
Often represented by the Greek letter omega (Ω).
Real-World Examples
“Their calculations placed the expected T 2 resistance coefficient between 0.005 and 0.5 ohms per Kelvin squared, depending on how strongly other charges screen the interaction.” Domain
