EM 98 A model for circuits Part 1: Current and resistance C. Light a bulb using a battery and a single wire. Observe and record the behavior (ie., brightness) of the bulb when objects made out of various materials are inserted into the circuit. (Try materials such as paper, coins, pencil lead, eraser. your finger, etc.) What is similar about most of the objects that let the bulb light? D. Carefully examine a bulb. Two wires extend from the filament...
(2) Five identical bulbs (numbered 1-4) are arranged as shown (a) Rank the brightness of from BRIGHTEST to DIMMEST (b) What would happen to the brightness of Bulb 1 if the wire was cut between bulbs 2 and 3? Explain 5 (c) You have 3 bulbs, some wire, and a battery. Draw two circuits: One circuit must have have all 3 bulbs be brighter than the ones in the other circuit (3) Find the the current and potential difference for...
