Volts: Went up to 117.99 V <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;">b. Amps: 11.80 Amps <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;">The battery went in to fire.

<span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;">11. Make your own <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;">a. Volts: In between 13~24. It quickly went up to its maximum point, but also quickly went down to its minimum point. <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;">b. Amps: The range of Amps was 1.30~2.40. It showed the movement as same as the volts did. <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;">c. Explain what happened with your circuit: <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;">The light was constantly on, but the brightness was changing. It got bright, then less brighter, and kept repeated it. <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;">d. Describe/draw your circuit below:

<span style="color: #800000; font-family: 'Arial Black',Gadget,sans-serif; font-size: 24px;">CREATE <span style="color: #800000; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;">Now start your circuit project. Get the materials and instruction from Ms. Bradfield.
