คุณลักษณะ

• Use of 6th grade electric power
• This is an experimental device that can confirm that the degree of heat generation varies depending on the thickness of the electric heating wire even if the voltage is the same.
• Styrofoam or wax sheet is set on the electric heating wire, and the power supply is supplied from dry batteries or power supply.
• The Styrofoam or Mitsuro sheet will melt and fall down first from the side with the high heating value of Nichrome wire.
• * Due to the high temperature during the experiment, be careful not to touch the electric heating wire.
• * The color of the sheet may change depending on the lot.
