-6
Ib = 0.20 x 10 A 1
(b) (i) Show triangle minimum 4 x 3 1

Tunjukkan segitiga minimum 4 x 3
Correct substitution: Penggantian yang betul: 1
-3
(37.5 - 10.0) x 10 A
-6
(0.30 - 0.03) x 10 A
Correct answer: Jawapan betul: 1
5
1.02 x 10
(ii) Ic/Ib = Gradient of graph / kecerunan graf 1
5
= 1.02 x 10 1
(c) Correct calculation: Pengiraan yang betul:

Ie = Ib + Ic
-3
-6
= (0.30 x 10 ) + (37.5 x 10 ) 1
Correct answer: Jawapan betul:
0.0375A 1

(d) The eyes should perpendicular to the scale reading of ammeter. 1
Mata mesti berserenjang dengan skala ammeter.
12

11. (a) (i) V decrease 1
V berkurang

(ii) Extrapolation line / Garisan ekstrapolasi 1
V = 1.0V 1
(iii) E.m.f / D.g.e 1

(b) (i) Show triangle minimum 4 x 3 1
Tunjukkan segitiga minimum 4 x 3

Correct substitution: Penggantian yang betul:

m = 0.48-1.0 1
0.77-0
= - 0.675 Ω 1

(ii) r = 0.675 Ω 1
(c) (i) Correct calculation: Pengiraan yang betul:

E = V + Ir 1
1.0= v+0.8(0.675)
