If two metal loops are near a battery (like in the picutre at the right), and turned toward it, which loop will have the largest amount of electric field flux passing through it? a. The loop closest to the battery will contain the most flux because the electric field is stronger near the battery b. The loop farthest from the battery will contain the most flux because the electric fi more spread out farther from the battery Since both loops are the same size, the contained flux will be the same for both. c. Which of the following statements is true? a. 2. Everything connected in series with a battery will have the same voltage (potential difference) across it. b. Everything connected in parallel with a battery will have the same electrical current through it. eetricalz C. d. Everything connected in parallel with a battery will have the same voltage (potential difference) across it. e. Everything connected in series with a battery will have different electrical current through it. A capacitor's time constant marks the time it takes for the capacitor to charge to 63% of capacity. How long is that? a. immediately after being connected to the battery. Dielectric b. after a time duration oft-CV c. after a time duration ofr- CR. Capacitor Burger 3. Battery Soda Buns of Steel d. after a time duration of t RV e. when pigs fly (i.e. never). Two resistors with the same power rating are connected in series across a voltage source. If the source increases voltage until one of the resistors fails, which resistor will fail first? a. The smaller resistance resistor will fail first. Crinkle-cut French Fry Resistor 4. The larger resistance resistor will fail first. The current is the same through both, so both fail together. b. c.Explanation / Answer
1) a) The closest to the battery will contain the most flux because the electric field is stronger near the battery
2) d) Everything connected in parallel with the battery will have the same voltage(potential difference) across it
3) c) The time constant is t = C R
4) c) The current is same through both (and they both have the same power rating), so both will fail together.
