1 ohm (Ω) is the unit of electrical resistance. It measures how much a material resists the flow of electric current.
To understand it better, consider Ohm’s Law, which states:
\[
V = I \times R
\]
Where:
- \( V \) is voltage (the electrical potential difference, measured in volts),
- \( I \) is current (the flow of electrical charge, measured in amperes),
- \( R \) is resistance (measured in ohms).
If you have 1 ohm of resistance, it means that if you apply 1 volt across a component, it will allow 1 amp of current to flow through it. In other words, the component resists the flow of current to such an extent that for every volt applied, only 1 amp flows.
In simpler terms, 1 ohm is the amount of resistance that allows 1 ampere of current to flow when 1 volt is applied across it.
