In the A C circuit shown, aligned & E=E₀ ( t+ ) and & i=i₀ ( t+ + 4 ) . aligned Then, the box contains

Options

  1. AOnly C
  2. BL and R in series
  3. CC and R in series or L, C and R in series
  4. DOnly R

Correct answer

C. C and R in series or L, C and R in series

Step-by-step solution

As current leads by 4 , so circuit must be more capacitive them inductive. Hence, it is either a C-R combination or L-C-R combination.
