Harder equations to know that are NOT On theequation sheet

E =ITV
P=NHF (n is number of phtons passing a fixed point per second)
total charge = number of electrons x (1.6x10^-19)
total number of electrons passing a fixed point , charge carries Charge/ 1.6 x10^-19
Number of electrons/ phot electrons emitterd Current/1.6x10^-19

hope this helps guys

Hey what do you mean by e=itv

And what are you talking about in the last few line, phot electrons.

Can someone QUICKLY outline to me the experiments that we have to know?

E=ITV is energy transferred is power times time

Same thing as g=bbc and f=sky :redface:

How do you usually answer 6markers
Do u make bullet points, tables or paragraphs

Paragraph and maybe a table

Only bullet point if you only have 2 minutes left

Moslty resistors and voltages or an experimemt for a thermiator using water bath.

Usually it's some sort of component testing.

•

Power supply

•

Ammeter in series

•

Voltmeter in parallel with the component

•

Variable resistor if changing current

•

Water bath if changing temp

•

Record V and I

•

Plot a graph and find the gradient

Thanks. How would you draw the water bath on a circuit diagram?

Hahahaahah this is by far the worst drawing ever but its how I would do it. Not sure if its right/not but hope it helps.

Extra marks if you draw a shark in there as well. :wink:

Good luck for everyone this morning!

You would just draw the symbol for a thermistor and then in your explanation state that to alter the temperature of the thermistor you place it in a water bath with a digital thermometer and vary the temperature :smile:
