B.5.8—Conventional current question 1

[Maximum number: 1]

A1.0 mF capacitor is connected in series to a 2.3kΩ2.3 \mathrm{k} \Omega resistor and a cell of negligible internal resistance.

Figure for Question B.5.8—Conventional current question 1 — IB Physics HL

The capacitor is initially uncharged. At time t=0 the switch is moved to position A. The initial current in the resistor is 3.9 mA .

Draw, on the circuit diagram above, an arrow showing the direction of the conventional current in the resistor for t>5.0 st>5.0 \mathrm{~s}.
