Before the saturation state of a diode at the plate voltages of 400 V and 200 V respectively the currents are `i_(1)` and `i_(2)` respectively. The ratio `i_(1)//i_(2)` will be

Options

A. `sqrt(2)//4`
B. `2sqrt(2)`
C. 2
D. `1//2`

Answer

C

Explanation

Before saturation region, linear region comes. In linear region
`l_(p)propV_(p)`
`implies" "(l_(1))/(l_(2))=(V_(p_(1)))/(V_(p_(2)))=(400)/(200)=(2)/(1)`
