Homework Statement The problem says. Shown are two circuits. In one circuit, a light bulb is connected directly to an AC source. In the second circuit, an identical light bulb is connected in series with an inductor and a capacitor to an identical AC source. a- is it possible for the bulb in...

oh i was doing the loop rule by accident. that's why i was setting them equal to zero.

more so help with the concept than anything else. A battery has an EMP of 12v and an internal resistance of 2 ohms. Is the terminal-to-terminal potential difference greater than, less than, or equal to 12v if the current in the battery is from a) from the neg to pos. terminal b) from pos to...

anyone have any ideas?

We recently did a Resistance in Circuits lab. My coded resistances were 33, 100 and 220. The measured resistance was 33.3, 101.6 and 219 So we did 3 setups. (Series, Parallel and Combination) Series = 351.8 measured ohms Parallel = 22.5 measured ohms Combinations = 101.5 measured...

Ok awesome. Now i got q= 1.603x10^-10 C n = 1.00x10^9 (seems rather large tho for the number of electrons)? thanks for all ur help. i really appreciate it.

thats rite. so i used F = K|q1||q2|/r^2 then i got q1 = 2.57x10^-20 C and like u said q1 = q2 for the number of electrons... q = ne so i got n = 0.16

well i know the charge resides on the surface of the sphere. Eo(flux) = Qenclosed so after taking the closed derivative i end up with E=1/4piEo Q/r^2 which is simply E = KQ/r^2

two spheres are

Of the charge Q initially on a tiny sphere, a portion q is to be transferred to a second, nearby sphere. Both spheres can be treated a particles. For what value of q/Q will the electrostatic force between the two parts have 1/4 of the maximum possible value? q1=Q when the charge is...

simple concept i did not realize and i was jumping the gun and not establishing the charge distribution. But the overall charge(q) is 3/8. So then its 3/8 of the initial force. i got the answer. thanks!

Identical isolated conducting spheres 1 and 2 have equal charges and are separated by a distance that is large compared with their diameters. The magnitude of the electrostatic force acting on sphere 2 due to sphere 1 is F = 8.9 N. Suppose now that a third identical sphere 3, having an...

The suspension system of a 1700 kg automobile "sags" 13 cm when the chassis is placed on it. Also, the oscillation amplitude decreases by 62% each cycle. Estimate the values of (a) the spring constant k and (b) the damping constant b for the spring and shock absorber system of one wheel...

to be honest, I am not sure i did. silly. but is the analysis i did correct for the problem?

A water intake at a pump storage reservoir (Fig. 14-44) has a cross-sectional area of 0.87 m2. The water flows in at a speed of 0.35 m/s. At the generator building, at distance D = 180 m below the intake point, the cross-sectional area is smaller than at the intake and the water flows out at 9.8...
