Homework 4 & 5 Name: Date:

1. Consider a voltage verse current graph. If you have a resistors with a résistance of 200 ohms

what is the voltage a x= 14 (I= 14 amps)

2. If you have a power supply that produces 17 volts at a constant rate and a resistor of 55 ohms

what is your current.

3. Consider this:

You have a set of 100 ohm resistors, 300 ohm resistors, and 500 ohm resistors

A. Using the as many of the resistors as needed from above, draw a circuit that has 1000 ohms of

resistance.

B. Using the as many of the resistors as needed from above, draw a circuit that has 150 ohms of

resistance.
