, (b) When the p.d. across the bulb was 3.0 V, the student recorded a value of 1.29A for
the current.

In his conclusion he stated
This will give an accurate value for the working resistance, as the
value of current is precise.
Assess the validity of the student’s statement. You do not need to carry out
a calculation.
