An dielectric current has both DC and AC...

An dielectric current has both DC and AC components . DC component of BA and AC component is given as I = `6sin`omega`t. So `underset(rms)(I)` value of resulatant current is

A

8.05A

B

9.05 A

C

11.58 A

D

13.58 A

Text Solution

Verified by Experts

The correct Answer is:
B
`I_(dC) = 8 A`
`I_(rms) = (6)/(sqrt(2)) A`
net `I_(rms) = sqrt(I_(dc)^(2) + I_(rms)^(2))`
` = sqrt(8^(2) + ((6)/(sqrt(2)))^(2)) = sqrt(82) = 9.05 A `
