If R , X L and X C represent resistance, inductive reactance and capacitive reactance. Then which of the following is dimensionless:

Options

  1. AR   X L   X C    
  2. BR X L X c
  3. CR X L X c
  4. DR X L X c

Correct answer

B. R X L X c

Step-by-step solution

As resistance, inductive reactance and capacitive reactance have same unit ohm. So, all three have same dimension. Thus, R X L X C is dimensionless.
