Question 1

Circuit 4

For the circuit shown in the figure, calculate total resistance R₁_7, current /3 through

resistor R3, voltage drop U6 across resistor R6, power P4 dissipated by resistor R4,

voltage across the source U and current through the source / !

The following values are given:

R₁ = 190, R₂ = 340, R3 = 20 02, R4=890, R5 = 370,

R6 220, R7=810, power of the source P = 8 W
