If coil is open then L and R become
Options
- A, 0
- B0,
- C,
- D0,0
Correct answer
B. 0,
Step-by-step solution
When coil is open, there is no current in it, hence no flux is associated with it, ie, =0 . Also, we know that flux linked with the coil is directly proportional to the current in the coil, ie, i or =L i where L is proportionality constant known as self-inductance. L= i =0 Again since i=0 , hence, R= .
