PhysicsMedium226×since 2002Q6405The electric current through a wire varies with time as I=I0+βtI=I_0+\beta tI=I0+βt, where I0=20 AI_0=20 \mathrm{~A}I0=20 A and β=3 A/s\beta=3 \mathrm{~A} / \mathrm{s}β=3 A/s. The amount of electric charge crossed through a section of the wire in 20 s20 \mathrm{~s}20 s is :A80 CB800 CC1000 CD1600 CCheck answerSkip
