A Level Physics: Resistivity of a wire practical experiment / required practical

[@godfred8618]

could you make a video on potentiometers and show its comparison to variable resistors please? great video

[@zhelyo_physics]

excellent idea, thanks!

[@TheObloINATOR777]

any practicals on capacitors and electric fields videos?

hi, why is the fixed resistor needed in the circuit?

[@zhelyo_physics]

Typically to limit the current, it's possible for the wire to overheat quite easily.
