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.
• You can also compare the difference in how the two types of electric heating wires heat up water by using the supplied water griddle while the instrument is upside down.
• Ideal for inserting a thermometer to see how the water temperature changes.
• * 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.
