If ( R , C ), and L be the resistance, capacitance, and inductance in the circuit in which ac of frequency f is set up, then which of the following have the dimensions of R ? (a) fC (b) fL (c) (1 / fC ) (d) ( L / f )

Options

  1. Aonly a & b
  2. Bonly b & c
  3. Conly c & d
  4. Dall

Correct answer

B. only b & c

Step-by-step solution

( = RC R = C ) ( aligned & [R]= [ 1 f C ] & = L R R= L =(f . L) aligned ) ( b ~ &~ c ) are correct.
