Question

What is the SI unit of LCR?

Answer 1

The SI unit for LCR (which stands for Inductance (L), Capacitance (C), and Resistance (R)) is a combination of the SI units for each of these quantities.

1. Inductance (L): The unit of inductance is the henry (H).  
   

   \[
   1 \, \text{henry (H)} = 1 \, \frac{\text{volt} \cdot \text{second}}{\text{ampere}}
   \]

1. Capacitance (C): The unit of capacitance is the farad (F).  
   

   \[
   1 \, \text{farad (F)} = 1 \, \frac{\text{coulomb}}{\text{volt}}
   \]

1. Resistance (R): The unit of resistance is the ohm (Ω).  
   

   \[
   1 \, \text{ohm (Ω)} = 1 \, \frac{\text{volt}}{\text{ampere}}
   \]

So, LCR doesn’t have a single SI unit. Instead, each component has its own unit:  

1. L (Inductance): henry (H)  
   

1. C (Capacitance): farad (F)  
   

1. R (Resistance): ohm (Ω)
