Question

The switch in the figure (Figure 1) has been in position a for a long time. It is changed to position b at t=0s .

Problem 23.45 t 0 The switch in the figure (Figure 1) has been in position a for a long time. It is changed to position b at t 0 s Figure 1 of 1 9.0 V 50 2.0 MF Part A What is the charge Q on the capacitor immediately after the switch is moved to position b? Express your answer using two significant figures Q 18 C Submit My Answers Give Up Correct Part B What is the currentIthrough the resistor immediately after the switch is moved to position b? Express your answer using two significant figures I> 18 mA Submit My Answers Give Up incorrect; Try Again; 5 attempts remaining Provide Feedback Continue

Explanation / Answer

Part A :

charge Q = capacitance C X voltage V

Q = C X V

Q = 2 X 10-6 X 9

Q = 18 X 10-6 C

Q = 18 C

Part B )

i = V / R

i = 9 / 50

i = 0.18 A

i = 180 mA
