6. Drag the ammeter over a wire. How many amps are flowing through this circuit? _____ Make A Simple Circuit: Battery, 1 bulb, and wires. 7 Grab one battery and one lightbulb as shown. 8. Add some wires to your circuit to make the bulb light up (make sure 1 wire goes on the side of the bulb, and one wire goes on the bottom of the bulb.) 9.

Build a simple electric circuit using a battery as the electrical energy source, and a small light bulb as the electrical load (I suggest using a 6-volt “lantern” battery and a miniature incandescent light bulb rated for either 6 or 12 volts). Use “jumper” wires with metal clips at the ends to join these two electrical devices together:

Draw a picture of a simple circuit on the blackboard or display Electrical Circuit on the overhead. Ask if there are any questions. If not, ask one of the students to explain the drawing on the blackboard or the overhead.

SIMPLE ELECTRIC CIRCUITS SIMPLE ELECTRIC CIRCUITS Preparatory Questions: (also read this guide sheet, which contains some of the answers!) 1. State Ohm’s Law, defining every term in the equation. 2. If a bulb connected directly to a 6 V battery glows brightly when 1 A of current passes through it, what is the resistance of the bulb at that point?

Lab 5: Simple Electrical Circuits Introduction: In this laboratory you will explore simple DC (direct current) electrical circuits. The primary goal of the lab will be to develop a model for electricity. A model is a clear mental picture that helps to explain how a physical system behaves and allows you to correctly predict what will happen in

E x a mp l e 1 : The circuit is a simple series circuit and so the current is the same at all points. I1 = I2 = 3 A. The potential differences across the two resistors must add up to the total EMF so V1 = 4 V. E x a mp l e 2 : 4 A flows through a and into the junction, 3 A flows out through b so I1 = 1 A. ...
