Question 575: Current Electricity

Question

In the following electrical network, the value of 1 is

Accepted Answer

$$\begin{aligned}
& \mathrm{I}_4=\mathrm{I}_1+\mathrm{I}_2+\mathrm{I}_3=1+2+3=6 \mathrm{~A} \
& \mathrm{I}_6=\mathrm{I}_4-\mathrm{I}_5=6-1.2=4.8 \mathrm{~A} \
& \mathrm{I}_8=\mathrm{I}_6+\mathrm{I}_7=4.8+0.8=5.6 \mathrm{~A} \
& \mathrm{I}_{10}=\mathrm{I}_8-\mathrm{I}_9=5.6-0.5=5.1 \mathrm{~A} \
& \mathrm{I}=\mathrm{I}_{10}-\mathrm{I}_{11}=5.1-1.7=3.4 \mathrm{~A}
