A series RC circuit has R = 5 Ω and C = 10 μF. The current in the circuit is 5 sin 20000t. The applied voltage is
Answer: Option
Explanation:
Z = R2 + XC2 = 50
V = 550 sin(20000 t - 45°)
V = 252 sin(20000 t - 45°)
17.
A capacitor stores 0.15C at 5 V. Its capacitance is
Answer: Option
Explanation:
Q = CV or 0.15 = C(5) or C = 0.03 F.
18.
A 0.5 μF capacitor is connected across a 10 V battery. After a long time, the circuit current and voltage across capacitor will be
Answer: Option
Explanation:
When the capacitor is fully charged, i = 0 and voltage across capacitor is equal to battery voltage.
19.
For node 1 in figure, KCL equation is
none of the above
Answer: Option
Explanation:
i(t) is the incoming current. The currents leaving node 1 are 
20.
In the circuit of figure, the switch is closed at t = 0. At t = 0+ the current through C is
Answer: Option
Explanation:
Capacitor behaves as a short-circuit at t = 0.
