    Complex Capacitor Circuit (for me)

    Homework Statement 1. V for C1 2. Let's Say "C" is Resistor then C1 = R1 etc. how to get Eq Resistance for this Circuit ?[/B]Homework Equations Faraday's Law, Kirchoff Law The Attempt at a Solution [/B] for no 1 :I just want to make sure. point A is transfering negative charge to C2 and...

    Calculate resistance if the switch is closed 2 battery with different voltage

    i get it now after searching some images. because it has junctions we can Kirchhoffs Law I I1 + I3 = I2, because I3 = 0 then I1=I2 using Kirchhoff's Law II find loop for both sides E2 = I212 + 0*4 ---> 12 = 12I2 ---> I2 = 1 E1 = I1R + I212 ---> with I=1 ---> 18-12 = R, R=6 ohmsThx for your...

    Calculate resistance if the switch is closed 2 battery with different voltage

    I = V / R if I = 0 with R = 4 then I = 0/4 that's mean on that R2 doesn't have more voltage (V=0) because all the voltage used by R3 ? because the batteries have different voltage, the higher voltage will charge the lower one until they have same voltages. then Voltage on R3(after upper node)...

    Calculate resistance if the switch is closed 2 battery with different voltage

    1.) what i thought is because the switch is open, the current will ignore R2 and E2, and just go through R and R1(R and R1 will be series) that will be ez to find out R for no 1. V / I = R 18 / 0.5 = 12+R R = 24 2) when switch is closed, it has 2 battery and its voltage will be 18V (if both of...

    Calculate resistance if the switch is closed 2 battery with different voltage

    Homework Statement before that, can you tell me about "current flow in this circuit" if : A. the switch is open B. the switch is closed the Question is No. 1 Calculate the resistance of R if the value of the current I in the figure is 0.50 A. ( i think it is related to no 2) no 2. Calculate...

    Find electric Field at a point A

    Enet = (E12 + E22)1/2 Enet = 2.23 x 103 do you mean like that bro ? anything wrong from my answer ? then for another question like this( at different point), just do this step ?

    Find electric Field at a point A

    Hi Guys, I've been learning electric field, and i want to ask about this question.EF net = EF1 + EF2 my EF1 = 9 x 109 * 4 x 10-8 / (0.6)2 = 1 x 103 (From Q1) EF2 = 9 x 109 * 2 x 10-8 / (0.3)2 = 2 x 103 (From Q2) then EFnet = (2+1) x 103 = 3 x 103 and what i get from key answer is 2.2 x 103...
