music

I enjoyed learning piano in this year. I had never played piano ever.

I felt difficult to playing guitar. It was too big to hold. And it has too many string! It made me too complicate to hold chord.

ammeter: A device used to measure current in a circuit

wire: A thin, flexible thread of metal

resistor: An electrical device that resists the flow of electrical current

bulb: In a circuit, this shows if electricity is flowing by lighting up

switch: A device that opens or closes a circuit

battery: A device that converts chemical energy to electrical energy

1.A circuit containing a battery, a light bulb, connected by wires-

2.Now add a switch into the circuit you just made, what happens when the switch is open or closed?-

3. Now click on the battery and increase the voltage it supplies to the  circuit. What happened?-
