Q4. 3.Resistance are measured in
Ans. 
Resistance is measured in ohms.
• Resistance is a property of an electrical component or material that opposes the flow of electric current.

• The unit of measurement for resistance is the ohm (Ω).

• Resistance can be measured using a multimeter or an ohmmeter.

• For example, a resistor with a resistance value of 100 ohms would be written as 100Ω.
