Determine the current through Z3 in the circuit of Figure P4

Determine the current through Z_3 in the circuit of Figure P4. 51. v_s1 = v_s2 = 170 cos(377t) v Z_1 = 5. 9 0. 122 ohm Z_2 = 2. 3 0 ohm Z_3 = 17 0. 192 ohm

Solution

VOLTAGE ACROSS Z3=VS1+VS2

170<0+170<0=340<0 VOLTS

CURRENT THROUGH Z3=(VOLTAGE ACROSS Z3)/Z3=(340<0)/(17<0.192)=20<-0.192 AMPERES.
