Question

sapling learning Consider the circuit shown in the diagram below. Before the switch is closed, both capacitors are uncharged. Immediately after the switch is closed, what is the amount of current supplied by the battery? 4.5 uF 90 Q 12 V Number 70 Q 20 Q nitial 2.0 HF -L Assuming the switch remains closed for a long time, which capacitor will be the first to reach 95% of its final charge level? O The 4.5-UF capacitor O The 2.0-UF capacitor What is the time constant for charging this capacitor? Number

Explanation / Answer

Here, Iinitial =   12/13.26

                   = 0.9049 A

Here, 4.5 microF capacitor will be first to reach 95% of its final charge level .

Time constant for charging this capacitor = 15.55 * 4.5

                                                                    = 69.975   microsec
