Question

Name: Alwi 11) As source A) increases B) decreases C) does not change more resistors are added in parallel across a constant vollage source, the power supplied by the 12) A 6.0-gF capacitor is connected in series with a 5.0 M resistor, and this combination is connected across an ideal 15-V DC battery. How long does it take for the current to decrease by 13) An RC circuit is connected across an ideal DC voltage source through an open switch. closed at time 0s. Which of the following statements regarding the circuit are correct? more than one correct choice.) The switch is (There may be A) The charge stays constant with time B) The capacitor will not fully discharge C) The capacitor will fully discharge D) The current is constant E) The current is not constant BONUS: The Borg, from Star Trek, have a popular phrase they like to say (and it showed up muliple times in the notes). What is that phrase?

Explanation / Answer

11] Power supplied by the source = P = V2/Req

If more resistors are connected in parallel, Req will be smaller and so for a constant V, the power supplied will thus be smaller. [Option - B].

12] RC = 6u x 5M = 30s

so, I/Io = e-t/30 = 1/4

take ln on both sides to get:

t = - ln(1/4) x 30 = 41.588 s.
