Q1. What is the unit of resistance
Ans. 
The unit of resistance is Ohm (Ω)
• The unit of resistance is denoted by the symbol Ω (Ohm)

• Resistance is measured in Ohms, named after German physicist Georg Simon Ohm

• 1 Ohm is equal to 1 Volt per Ampere (V/A)

• Common examples of resistance include resistors in electronic circuits
