Ohm's law U=I.R so U=0.303x30=909mV

V=IR so V = 0.303 x 30 then V= 9.09 volts drop across the 30 ohm resistor here. or 10-0.909 as shown = 9.09v

0.909v drop across the 3 ohm resistor plus the above give the circuit total of 10v

Yes actually, I skipped part of the equation :D

We all make errors, it's completely normal (you could soon find loads of mine !). It is worrying if you find someone who firmly believes that they never do.
