What do you know about resistance?
- A force that opposes the flow of current in a wire is called resistance. In simple words, it is the refusal or disagreement with something.
- It is denoted by the Greek letter omega (Ω) and is measured in ohms.
- ohms has been named after the German Physicist Georg Simon Ohm who studies the relationship between current, voltage, and resistance.
- For example, if a child is fighting against his kidnapper he would show resistance.
- Similarly, wind against plane wings is another example of resistance.
