A2 AQA practical help

im really bad at setting up circuit, so i just wanted to ask how you connect a component into a circuit...do you attach the negative side (as on the component, ie conventional current direction) of the component to the negative terminal of the battery???...im not even sure if this makes any sense :confused:

for aqa A2 physics A how many sig fig do u use in your results table???

does a variable power supply work in the same way as a variable resistor???

thnx in advance

Variable power supply does not work the same way as a variable resistor, you should really put in 3 sig figs in tables all depends on the amount of sig figs there are. And the diagrams should show what way to organise the circuit out, though it does not matter with resistors.
