Question

3) A new circuit with a capacitor (C = 8.5 , two resistors (R1-6 and R2 8.8 ), a switch and a battery (unknown V) is created as shown. The capacitor is initially uncharged and the switch is open 0.61 A, what is the voltage of the The instant the switch is closed the current through the battery is measured to be battery? Ov- 9.03 V Ov-5.37 v Ov- 1.83 V Ov 3.66 V Submit 4) After a long time what is the current through R2? 012 = 0.61 A 012 = 0.416 A 12=0.124 A O12- 0.247 A 012 = 0 A Submit 5) After a long time, what is the charge stored on C? Submit

Explanation / Answer

3) no current will through R2.

V = i R1 = 3.66 Volt

(4) now current will flow through R1 and R2 only.

I = V/ (R1 + R2) = 0.247 A

(5) Vc = I R2 = 2.18 Volt

Q = C V = 18.5 uC
