Question

1) What is the equivalent resistance of this circuit? What is the voltage across and current through resistor R3? R1-50 K = 8

Answer 1

24v Rg and Rs resistance, Their paralle. equivalent are paralle, ROR3 Reg. Rathg = 4912 4x12 4 112 = 32 Cincin becomes | 24v - Ru Au three resistance, or in Reg= series. Equivalent R + Rég + Ry = 5+ 3+ 8 = 162 (by current across the circuit 1 - - 34 = I.SA. Real

Iz R2 Iz Y in the segment containing Ra and Rg. gets divided into the circuit merrent I and Iz (say) and is Scown through both Rg and g are Rz. Since parame, potential will be drop in both resistors the same ie. Vz = Vz a Izkz IzR3 = 22 - Depo Dyxia - 313 Also, 12 tlg =1=105 - 313+13= 1.5 => 13 - 0.375 A Sog current through Rz= 0.375 A and voltage arroy Rz=13R3 = 0.375X12 – 4.5 V
