Basics of Electric Current | MCQs Quiz Current Electricity Share with your friendsCurrent Electricity Topic Based Quiz (Basics of Electric Current) General Instructions This quiz is based on Basics of Electric Current. Each question carries one mark. There is no negative marking. Keep a rough notebook with you for rough work. All the best! 1. A conductor carries a current of 1 A. In one second, the charge that flows through any cross-section of conductor is- 2 coulomb 3 coulomb 1 coulomb 0.5 coulomb 2. Across a metallic conductor of non-uniform cross-section, a constant potential difference is applied. The quantity which remains constant along the conductor is- Current Drift velocity Electric field Current density 3. The charge flowing through the cross-section of a conductor is given by Q = t^{5} + 2t coulomb. The instantaneous current through the conductor at t = 1 s is- 2 A 5 A 7 A 10 A 4. The current in a device varies with time t as I = 6t where I is in mA and t is in s. The amount of charge that passes through the device during t=0 s to t=3 s is- 10 mC 18 mC 27 mC 54 mC 5. If the amount of charge passed in time t through a cross-section of wire is Q = 8t - 2t^{2}, then average current from t=0 to t=2 second is- 0 A 4 A 2 A 8 A 1 out of 5 Time's up Share with your friends
