Suppose a collection of five batteries is connected as shown in the figure, in which B₁ = 4.6 V.
(a) What is the equivalent emf of the collection? Treat them as ideal sources of emf.
3.0 × V
(b) What is the current through the resistor if its value is 3.3 Ω?
0.909 × V
In the circuit, R = 33.0 kN and C = 0.10 uF. The capacitor is allowed to charge fully and then the switch is changed from position a to position b. What will the voltage across the resistor be 8.7 ms later?
2.1 × V
