The expected answers were:
(c) Table 2
VAB(V) |
12 V |
V1(V) |
6 V |
V2(V) |
6 V |
(h) V1 + V2 = (6 + 6) V = 12 V
(i) On comparing step (f) with step (h), the two are the same.
Table 3
RCD(Ω) |
705 Ω |
I(A) |
0.017 A |
(p) = = 705.88 Ω
(q) On comparing step (m) with step (p), the measured resistance, RCD is
equal to the calculated value.
Candidates did well in this question. Majority of them obtained accurate reading.
