    Kirchoff Laws
AI Thread Summary
The discussion centers on troubleshooting a circuit using Kirchhoff's Laws. The user expresses confusion about setting up loops in their homemade circuit. Respondents suggest simplifying the circuit by replacing resistors R2 and R3, which are in parallel, with a single equivalent resistor. They recommend applying Ohm's Law to find the current through R2 and R3, as they are connected directly across an 18V source. Finally, they advise using Kirchhoff's Voltage Law (KVL) to write an equation for the outer loop to solve for the unknown current and subsequently determine the voltage across R1.

Hello, I am quite confused about this circuit:

http://tinypic.com/view.php?pic=1zvtnxf&s=6

It's quite possible, that this circuit doesn't make any sense, it was made by me, out of curiosity.
I know there is a junction, but from there I just can't set up any loops which would make any sense.
Thank you for your help.

Anyone? Just give me a hint please?
 
Your R2 and R3 are in parallel replace them with a single equivalent resistor. Now draw somr loops,
 
No need to calculate the parallel combination of R2 & R3.

R2 and R3 are directly across the 18V source so just apply Ohms law to find the current through each of them.

As for the outer loop... write an equation using KVL. Everything is known except for the current so you can solve for that. Apply Ohms law to work out voltage across R1.
 

Thread 'The Physics of unloading sand from a barge'

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
