Constructing Marking Scheme
Two 4.0 Ω resistors are connected in series to a 12 V battery. Calculate:
R1 + R2 or 4.0 + 4.0 C1
= 8.0 Ω A1
V = IR in any symbolic formC1
12/8C1
1.5 AA1
(i) 4.0 + 4.0
= 8.0 Ω
(ii) 12/8
= 1.5 A
(i) 4.0 + 4.0 = 8.0 Ω
(ii) 1.5 A
(i) 1/4 + 1/4 = ½
R = 2.0 Ω
(ii) I = V/R
= 12/2
= 6.0 A
(i) 1/4 + 1/4 = ½
R = 2.0 Ω
(ii) I = V/R
= 12 / 2
= 1.5 A
(i) 1/4 + 1/4 = ½
R = 2.0 Ω
(ii) I = VR
= 12/2
= 6.0 A
(i) 1/4 + 1/4 = ½
R = 2.0 Ω
(ii) I = 6.0 A
