Question
When two resistors are connected in series across a 12-V battery, 1.1A flows. When they are connected in parallel across the same battery, 6.3A flows. What is the smaller resistor's value? 1.7 ? 8.4 ? 2.5 ? 0.55 ? When two resistors are connected in series across a 12-V battery, 1.1A flows. When they are connected in parallel across the same battery, 6.3A flows. What is the smaller resistor's value? When two resistors are connected in series across a 12-V battery, 1.1A flows.

12/1.1=a+b
12/6.3=ab/(a+b)
or smaller=2.5 ohm
