Thanks for all the help ! I understand it clearly now !

but since (KE)max decreases, doesn't it mean that the current decreases?

Homework Statement Photoelectric effect A beam of blue light falls on the cathode of a photocell so that electrons are emitted. The blue beam is then replaced by a yellow one with the same intensity and electrons are also emitted. What would happen to each of the following physical...

I have thought of two : One through the middle through all 3 resistors, and another one , turning left between middle and rightmost resistor to pass through the middle resistor. Which one is correct?

Homework Statement For 1 and 2 : Find the equivalent resistance for the resistor network provided Homework Equations For resistor in series : Req = R_{1}+R_{2}+...R_{n} For resistors in parallel : Req = (1/R_{1}+1/R_{2}+... 1/R_{n})^{-1} The Attempt at a Solution For...

Thanks for all the help !

I tried redrawing and saw that C35, C4 and C2 are connected parallel ; C6 and C1 are connected parallel . Then I combined them and C2345= 6mF C16= 6mF So the answer is 1/Ceq=1/6+1/6 Ceq=3mF?

Homework Statement Problem taken from : Fundamentals of Physics , Volume 2 ( 7th edition) Halliday , Resnick , Walker In the figure, a 20.0V battery is connected across capacitors with capacitances C1=C6=3.00mF and C3=C5=2.00C2=2.00C4=4.00mF What is the equivalent capacitance Ceq of...
