If I_(1), I_(2), I_(3) and I_(4) are the respective r.m.s. values of the time varying currents as shown in the four cases I, II, III and IV. Then identify the correct relations. |

Answer» `I_(1)=I_(2)=I_(3)=I_(4)` `int I_(2)dt` = area of `I^(2)-t` curve on time axis will be maximum for `III` than for and `I` and `II` and least `IV`. `I_(3) gt I_(1)=I_(2) gt I_(4)` |
