So how far have you gotten on your own?

rayhan619

so the current through 4.0 ohm resistor, I = V/R = 24 V/4 Ohm = 6 A
and the potential difference ?

Homework Helper

Using formula for series and parallel combination of resistances find the total resistance of the circuit.

rayhan619

If i did it right then the total resistance should be 12 Ohm
So I = V/R= 24 V/ 12 Ohm = 2 A.
Right ?
how do I get potential difference?

Homework Helper

2A is the current through 4 ohm. Find potential difference by using V = IR.

rayhan619

V = IR = 2A*4 Ohm = 8 V

Next question,
Find the current through 6.0 {Ohm resistor.

Homework Helper

Potential difference across 4 ohm resistor is 8V.
What is the pd across remaining circuit? From that find the current in each branch of the circuit.
