electrical resistance
The opposition that a material or circuit presents to the flow of electric current. Measured in ohms. A fundamental concept in physics and electrical engineering.
銅は電気抵抗が低い。
Copper has low electrical resistance.
温度が上がると電気抵抗も増加する。
As temperature rises, electrical resistance also increases.
超伝導状態では電気抵抗がゼロになるため、エネルギーの損失なく電流を流すことができる。
In a superconducting state, electrical resistance becomes zero, allowing current to flow without energy loss.
A compound of 電気 (electricity) and 抵抗 (resistance). The unit of measurement is オーム (ohm), represented by the symbol Ω. This is a standard term in physics education, appearing in middle school and high school science curricula.
Ohm's law (オームの法則) states that voltage (電圧) equals current (電流) times resistance (電気抵抗).
COMMON COLLOCATIONS:
- 電気抵抗が高い: to have high electrical resistance
- 電気抵抗が低い: to have low electrical resistance
- 電気抵抗を測定する: to measure electrical resistance
- 電気抵抗の値: the value of electrical resistance
SIMILAR WORDS:
- 抵抗: resistance — the general term, also used as a component name (resistor)
- 抵抗器: resistor — the electronic component
- 導電性: electrical conductivity — the opposite property, how well a material conducts
