BioNB 440: Homework 1

1. The variable resistor show below varies from zero to 1 kohm. Write the variation as F*1000 where F varies between zero and one. Compute the voltage across each of the three resistors as a function of F.

   

2. In the circuit shown below, the variable resistor is defined as in problem 1. Compute the current through each resistor as a function of F.
