Experimenter:? People in the same group:? Experimental date:

Experimental name: Exploring the current law in series circuit.

Experimental purpose:? 1. Skillfully design and connect experimental circuits.

2. Explore the current law of series circuit, and learn physical experiment methods such as induction.

Conjecture and hypothesis: (based on experimental questions)

Design experiment

Experimental circuit: (see attached figure)

Experimental equipment: student power supply? An ammeter? Small light bulb (two different specifications) switch? conductor

Experimental steps: 1. Connect the circuit according to the experimental circuit diagram (the ammeter is temporarily disconnected from the circuit).

2. Check the circuit, turn off the switch after confirmation, and see if the light bulb is emitting normally.

3. choose three points a in the circuit? b？ C, respectively, connect the ammeter to the circuit, close the switch and record the instructions of the ammeter.

4. Repeat this experiment with small light bulbs of different specifications.
