PhysicsEasy94×since 2002Q5886An alternating current is given by the equation i = i₁ sin ω\omegaωt + i₂ cos ω\omegaωt. The rms current will be :A12(i12+i22)12{1 \over {\sqrt 2 }}{\left( {i_1^2 + i_2^2} \right)^{{1 \over 2}}}21(i12+i22)21B12(i1+i2){1 \over {\sqrt 2 }}({i_1} + {i_2})21(i1+i2)C12(i1+i2)2{1 \over {\sqrt 2 }}{({i_1} + {i_2})^2}21(i1+i2)2D12(i12+i22)12{1 \over 2}{\left( {i_1^2 + i_2^2} \right)^{{1 \over 2}}}21(i12+i22)21Check answerSkip
