Answer 1

a, \(=>R5nt\left[\left(R1ntR3\right)//\left(R2ntR4\right)\right]\)

\(=>Rtd=R5+\dfrac{\left(R1+R3\right)\left(R2+R4\right)}{R1+R2+R3+R\text{4}}\)

\(=2+\dfrac{\left(3+1\right)\left(2+2\right)}{3+1+2+2}=4\left(om\right)\)

b,\(=>Im=\dfrac{20}{4}=5A=I5\)\(=I1234\)

\(=>U1234=5.\dfrac{\left(3+1\right)\left(2+2\right)}{3+1+2+2}=10V=U24\)

\(=>I24=\dfrac{10}{2+2}=2,5A=IA\)
