PhysicsLAB: Introduction to R | I | V

A parallel circuit connected to a 12-volt battery. One branch has a 2-ohm resistor, another a 1-ohm resistor and the last a 6-ohm resistor.

	Construct a circuit diagram.

As you fill in the following R | I | V | P chart for this simple parallel circuit remember that resistors in parallel experience the same voltage drop and that the main-line current divides through the branches.

A series circuit containing three resistors is connected to a 12-volt battery. The three resistors have resistance of 2 ohms, 1 ohm, and 6 ohms respectively.

	Construct a circuit diagram.

As you fill in the following R | I | V | P chart for this simple series circuit remember that resistors in series experience the same current flow and that the sum of the voltage drops must add up to the voltage of the battery.
