Created by StemPy LabA and a resistor are in parallel and together take . What current flows in the resistor?
← All Quizzes
← A 13 V charger is joined to a 4 V battery to charge it, so their emfs oppose each other round the loop. The loop's total resistance is 4 Ω. What charging current flows?The left branch has a 10 V battery and a 2 Ω resistor. The right branch has a 4 V battery and a 2 Ω resistor. A 4 Ω resistor is the middle branch. Both batteries have their positive terminals on the top wire. What current flows through the middle resistor? →
