Volts: it decreased very rapidly <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;"> b. Amps: also decreased very rapidly

<span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;"> 5. Use an inductor in your circuit. (One battery, one bulb) <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;"> a. Volts: increases rapidly and then slows down <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;"> b. Amps also increases rapidly and then slows down

<span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;"> 6. Use an AC Voltage in your circuit. What happens to the current? <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;"> a. Volts: increases then decreases <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;"> b. Amps: increases then decreases

<span style="color: #800000; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">Answer the Following Questions After You Complete Your Circuit: <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">1. Did you like making the circuit? Yes I did ! <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;"> 2. What did you like the least about making the circuit? Cutting the wires. <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;"> 3. What did you like the best about making the circuit? Soldering. <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;"> 4. Using complete sentences, explain how circuits can be applied in the real world. (List three) If there weren't any circuits, we wouldn't have any computer or we would have computers but they wouldn't work. Also, if there weren't any circuits, we would have electricity!!! There's also circuits in phones and without them we wouldn't be texting in our classes!(: <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;"> 5. Were you careful with the circuit, solder, and soldering iron? Yes, we were. <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;"> 6. Were you respectful and nice to other students? Yes, I let them borrow stuff. =<span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;"> 7. Did you take a picture of both your circuits and add them to this wiki page? I'm about to. = =<span style="color: #00ff00; font-family: 'Comic Sans MS',cursive; font-size: 17px;">THE PICTURE OF OUR CIRCUIT DISAPPEARED!!!!! = <span style="color: #800000; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20px;">ATTITUDE <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">1.
