in the attachment you'll find a question i have been asked to answer, iv had an attempt at the question but i would like to know from you experts whether i'm on the right track or not, and what calculations i need 2 do to get the answers if mine are wrong, thanks 4 all ur help

 

One way to check your answers is to take the voltage applied across all of the resistors since they are in series and divide it by the sum of all of the resistances. This will give you the current flowing in the loop.

Then take the voltage readings you have calculated and determine the voltage across each of the resistors. Divide each resistor value into the voltage drop you calculated for that resitor and that current should be the same as the current you calculated was flowing in the entire loop.
