Homework Statement
1. R = 470 ohms. Connect a jumper wire between points A and B. Measure the voltage across the load resistor. Explain why the load voltage with a shorted load is zero using Ohm's law.
2. Remove the jumper wire and open the load resistor. Measure the voltage between the AB terminals. Why is the load voltage with an open load approximately equal to the source voltage. Use ohm's law and kirchhoff's voltage law to explain.
Homework Equations
***Voltage source = 10V
The Attempt at a Solution
1. I am confused how to explain this. Would it simply be because the wire has no resistance it is taking all the current up? V=IR , V=0*r V= 0
2. I'm lost on this one. Opening the load resistor would just make it a 10V battery in series with a 470 resistor. That doesn't exactly make it near the source voltage?
edit: still lost :( not sure what else to add, noticed a lot of views
