How does the concept of duality apply to electrical circuits?

1-1.1 A six-cell storage battery having a nominal terminal voltage of 12 V is connected in series with an ammeter and a resistor labeled 6 S2. PROBLEMS 39 a) List as many random quantities as you can for this circuit. b) If the battery voltage can have any value between 10.5 and 12.5, the resistor can have any value within 5% of its marked value, and the ammeter reads within 2% of the true current, find the range of possible ammeter readings. Neglect ammeter resistance. c) List any nonrandom quantities you can for this circuit.
