Current Electricity and Electrical InstrumentMedium
Question
Consider a circuit with a constant current source of IC = 2mA with a capacitor of 2μF and resistor of 5kΩ (as shown in figure). At t = 0 the switch is closed. IC & IR denotes current in the capacitor & resistor branch respectively and VC represents potential difference across the capacitor. Choose the correct graph(s).
Options
A.
B.
C.
D.
Solution
At t = 0, capacitor act a short circuit & current in resistor branch = 0.
At t = ∞, iR = 2 mA ; iC = 0
At t = ∞, iR = 2 mA ; iC = 0
