I'm 100% confident that it was BB. The total resistance was 25 ohms

No exactly cos pd across build was 1.4 pd across resistor was 4 terminal pd =5.4
So lost volts was 0.6 and current was 0.1
R is therefore 6
Easy

For the sketch of the graph was it half the amplitude and double frequency?

EDIT: amplitude stays the same I get it I don’t need 30 people to point it out thanks T_T
