A network of resistors of resistance R1 = 10 ohms and R2 = 12 ohms extends to infinity towards the right. What is the approximate total resistance of the circuit in ohms?
Assume you measure voltage and current readings for a particular resistor as shown in the table. Use a spreadsheet application (such as excel) to plot voltage vs. current and find a linear fit. Use this to determine the measured resistance.
The accepted resistance, measured with a multimeter, is 468 ohms. What is the error in your measurement?
What is the current and voltage across resistors T, V, and X?
