I pada masing-masing resistor ...?

1/R total = 1/R1 + 1/R2 + 1/R3

1/R total = 1/4 + 1/2 + 1/3

1/R total = 0,25 + 0,5 + 0,333

1/R total = 1,083

R total = 1/1,0833

R total = 0,923 Ohm

I total

V = I × R total

10 volt = I × R total

10 volt = I × 0,923 Ohm

I = 10 volt/0,923 Ohm

I = 10,83 A

I pada resistor 1

V = I1 × R1

10 volt = I × 4 Ohm

I1 = 10 volt/4 Ohm

I1 = 2,5 A

I pada resistor 2

V = I2 × R2

10 volt = I2 × 2 Ohm

I2 = 10 volt/2 Ohm

I2 = 5 A

I pada resistor 3

V = I3 × R3

10 volt = I3 × 3 Ohm

I3 = 10 volt/3 Ohm

I3 = 3,33 A

Pembuktian

I = I1 + I2 + I3

I = 2,5 + 5 + 3,33

I = 10,83  A
