When an electrical circuit is closed, current can flowall theway around it without stopping, and the electricity is on.When a circuit is open, a gapor obstacle keeps the current from going all the way around, and the electricity is off. 5 For each circuit shown, do the following: 1. Predict. If this were a real-life circuit, would the light bulb turn on? Why or why not? 2. Investigate. Build the circuit using a miniature light bulb base (also called an E-10 light bulb base), a 1.2-volt flashlight bulb, a solar cell, and two pieces of insulated wire with one inch stripped off each end. These materials can usually be found at localoronlineelectronicsretailers. Ifyoucannotfindasolarcell,youmaysubstitute a D battery. 3. Observe and Conclude. Cup your hands around the bulb so you can see if it lights up. Record what A B C D Which circuits WILL WORK?
