Question


Problems 12 and 13 are related. In the circuit shown to the right, the sum of the resistances of resistors R, and R, IS 16 Ohms. 4Ω R, 12) What is the current in the right branch of the circuit? A. 0.25 A B. 0.50 A C. 1.00 A D. 2.00 A R2 13) why? Resistor R, and the 4-Ohm resistor are now swapped. How does the current through the battery change, and A. The current does not change, because the resistance does not change. B. The current increases, because the total resistance will always decrease. C. The current decreases, because the total resistance will always increase. D. The change in current cannot be determined without knowing the resistances of R, and R
