Homework Statement A K shell electron is ejected from a tungsten atom. The result of this is the emission of a characteristic x-ray proton. (The binding energy of the K shell in tungsten is 69.5keV. The binding energy of the L shell in a tungsten atoms is 10.5 keV). a) If the vacancy in the K...

which ones would be in parallel and series? and what do you mean by starting from the farthest point of the battery? start at the 2ohms resistor?

Homework Statement What is the approximate equivalent resitance of the five resistors shown in the circuit show below? http://img515.imageshack.us/i/circuit.png/Homework Equations The Attempt at a Solution How do I solve this without voltage given?

Yeah the current in R1 and R2 does = the current in R4 and R5. I'm just wondering why would that work? Thanks vk6r0.

ok i figured it out. is the answer suppose to be 175 ohms?

I found the current going through all the resistors so can I just use Req = V / I? V being 24 and I being I1 + I2 + I3 + I4 + I5.

Homework Statement Find the equilivant resistance in the wheatstone bridge circuit. Here is a picture: http://sub.allaboutcircuits.com/images/00485.png Homework Equations The Attempt at a Solution I know R1 and R2 are in parallel and R4 and R5 are in parralel but I'm getting confused with R3...
