Penjelasan:

Part A

i) To found the ammeter reading I1 you must found the total of the resistance first

Rs = 4 Ohm + 2 Ohm

Rs = 6 Ohm

Nah, the electrical voltage in 4 Ohm just same with the electrical circuit. So the electrical voltage of the electrical circuit is 4 Volt

I1 = V/R

I1 = 4/6

I1 = 1,5 A

ii)

V1 = V2, so the Voltmeter of V2 is 4 Volt

Part B

i) Found the total of the resistance

1/Rp = 1/4 + 1/2

1/Rp = 1/4 + 2/4

1/Rp = 3/4

Rp = 4/3 Ohm

ammeter reading :

I = V/R

I = 8 : 4/3

I = 8 × 3/4

I = 6 A

current i1 and i2 :

i1 : i2 = 1 : 2

current i1 :

= 1/3 × 6

= 2 A

current i2 :

= 2/3 × 6

= 4 A
