Answer:
I₀ = 0.2 mA
Explanation:
- Just after being connected, as the voltage between plates of a capacitor can't change instantanously, the initial voltage through the capacitor must be zero, so it presents like a short to the battery.
- So, in these circumstances, as the battery only "sees"a resistor, the initial current can be found applying Ohm's law to the resistor, as follows:
- The initial current (that will be diminishing as the capacitor charges), is 0.2 mA.
