R2 = 20 N and R3 = 100 Ω. 1) Since R2 and R3 are in parallel, we can use equation (3) to calculate the equivalent total resistor R23 . 2) After that since R1 and R23 are in series, we can use equation (2) to calculate the overall total RT. 3) The battery V=9 volts is known, Ohm's can be applied to RT, total current can be calculated, and the total current is equal to I1 4) With I, and R1, Ohm's law can help us to get V1 5) V1 +V½ (or V3) = 9 volts, we get V2 6) Again, use Ohm's to get I2 and I3.

Q = Qo e* (C36) d) The capacitor charge in the circuit below decays exponentially when the capacitor has an initial charge of Qo: URC. Give brief physics (not math!) explanations for the observation that the time constant (how long it takes to discharge) is proportional to both C and R. Why is the time constant proportional to R (i.e. why does it take longer when R is bigger)? Why is the time constant proportional to C (i.e. why does it take longer when C is bigger)? R C

A parallel plate capacitor has an air-filled gap.  It is attached an EMF and charged it to charge Qo and voltage difference ΔVco.  Two different experiments are done.   Case A: The gap between the capacitor plates is then filled with Teflon with the capacitor still connected directly across the terminals of the EMF. Case B: The capacitor is disconnected from the EMF first before the gap in between the plates is then filled with Teflon. Which statement is true after the Teflon is inserted into the gap? 1.) In case A, ΔVc is unchanged but Q increases to keep the net E field between the plates unchanged. In case B, Q is unchanged but ΔVc decreases due to a smaller net E field between the plates. 2.) In case A, Q is unchanged but ΔVc decreases due to a smaller net E field between the plates. In case B, ΔVc is unchanged but Q increases to keep the net E field between the plates unchanged. 3.) In case A, Q is unchanged but ΔVc increases due to a larger net E field between the plates. In case…
