Q1.Two identical batteries, each with an emf of 18 V and internal resistance of 1 Ohm, are wired in parallel by connecting their positive terminals together and connecting their negative terminals together. The combination is then wired across a 4-Ohm resistor. The current in each battery is: (Answer: 2.0 A).
Q2. A single loop of wire with a radius of 7.5 cm rotates about a diameter in a uniform magnetic field of 1.6 T. To produce a maximum of 1.0 V, it should rotate at: (answer: 35 rad/s).
