But is it directly proportional?

The y-axis would be in oC and would show the values for the maximum temperatures that the room reached at equilibrium and the x-axis would be the power.

Homework Statement A typical room is heated with an electric heater on which the power (and thus heat output) can be varied. What do you think the relationship might be between the power supplied to the heater and the resulting warmer temperature the room reaches? Ie if you were to plot a...

Sorry should have said in the original post - it's this one that I've got and want to use http://www.lowenergysupermarket.com/collections/energy-monitors/products/plug-in-energy-monitor

Hi guys, For a science experiment I've got to measure the power consumption of my circuit of a 100W incandescent light bulb connected to the mains AC, with a dimmer switch to vary its brightness. I was planning on just using one of those plug-in energy monitors with a digital display but...

That would be great but I don't believe that my physics store has this equipment. Is there any way to do it by building a box out of the insulator and putting an electric heater inside or something?

Hi, I'm doing a group investigation on external wall insulation for my school building. The walls do not have a cavity and thus it has been proposed to put insulation over the exterior render of the wall. This is a fairly common building procedure. However, my task is to investigate the...
