//Problem 41.04: The current output of an attenuator is 50 mA. If the current ratio of the attenuator is 1.32 Np, determine (a) the current input and (b) the current ratio expressed in decibels. Assume that the input and load resistances of the attenuator are equal.

//initializing the variables:
I2 = 0.05; // in Amperes
rin = 1.32; // in Np

//calculation:
//current input, I1
I1 = I2*%e^(rin)
//current ratio in decibels
rid = 20*log10(I2/I1)

printf("\n\n Result \n\n")
printf("\ncurrent input, I1 is %.4f A",I1)
printf("\ncurrent ratio in decibels is %.2f dB",rid)
