A bit of help with KCL and ohms law please

[twister16th]

i have attached a picture showing the problem;
just wanting to know if my working out and reasoning is correct please.

The Attempt at a Solution

i have used KCL to answer (a) and (b) and have answers 0.6 and 1 respectively.

for (c) and (d) i have used the equation v1=r1/(r1+r2)*v
and have answers 1 and 5 repectively.

for (e) i used power equation p=VI where V is 6 and I is 1 and have the answer 6.
thanks in advance for any help i get :)

The first two look OK.

What is the voltage across a resistor if it is 12 K and it has 0.4 mA flowing in it?

 

[twister16th]

as in use Ohm's law to find it out?

 

[vk6kro]

Yes, you can see two resistors that add up to 12 K.

You need the total voltage across them.

so v1=0.8 and v2 =4.0?
oh and thankyou for your help :), its really appreciated.
