A loop containing N identical resistors includes a battery with an emf of 10 V. If we start the loop at the battery's negative terminal, proceed through the battery and then through the resistors back to the negative terminal of the battery, the potential difference across each resistor and the number of resistors could be
1.3 resistors, 7 V
2.5 resistors, 2 V
3.9 resistors, 1 V
4.2 resistors, 5 V

Question 2

Three wires, each carry 2 A into in a junction. From that junction emerge two other wires carrying the current away. What could the current in those two wires be?
1.2 A each
2.6 A each
3.3 A each
4.4 A each
