In the circuit shown, calculate the current $${\mathrm{I}}_3$$. Give value in the directions shown (e.g. if the actual direction of current is opposite to one of these, write it as a negative value). Write answer in milli-amperes. R1 $$=0.8$$ kilo-ohm, R2 $$=0.5$$ kilo-ohm, R3 = 0.7 kilo-ohm, R4 $$=0.4$$ kilo-ohm R5 $$=0.6$$ kilo-ohm, $$\mathrm{V}1=1$$ volts, $$\mathrm{V}2=$$ 2 volts
