I need help. I don't know how to write a proper method and I don't know what to prove in my practical. And i don't know what to compare in my results and analysis and if any graphs should be included.
Practical Sheet:
Perform a first-hand investigation, gather information and use available evidence to demonstrate the relationship between current voltage and power for a model 6V to 12V electric heating coil.
Then it mentions
W = V.I.t = Mcat
P=W/t
Set up the following equipment to compare the power output in the form of heat (m.c.aT/t) to the power input in the form of electrical energy (V.I)
Use a voltage of approximately 12V and a beaker containing approximately 100ml of water. You will need to record the exact measurements of the mass of the water on the day.
(shows diagram)
And it shows the setup of the practical
