Question For the series-parallel network shown in the following figure, find: (a) the supply current, (b) the current flowing through each resistor, (c) the potential difference across each resistor,...

Hi could i please have the workings out and answer for the question attached.

If possible could you write down any formulas used.

I have asked this question 3 times and have had 3 different answers so far...

Thank you! :)
