2.26 The currents i, and i, in the circuit in Fig. P2.26 are 4 A and -2 A, respectively. PSPICE MULTISIM a) Find ig. b) Find the power dissipated in each resistor. c) Find vg. d) Show that the power delivered by the current source is equal to the power absorbed by all the other elements. Figure P2.26 11 0 E100 30 N 100 V 15 N 16 0

Two light bulbs are connected to a voltage source as shown. Us U₁ U₂ P₁ 1 P₂ R The voltage source has a output voltage Us of 230 V. Each light bulb requires 115 V. However, the two light bulbs have different power. P, equals 60 W while P₂ equals 100 W. Please find the resistance R so that both light bulbs have the same voltage of 115 V.

Find the power absorbed by each of the elements in the given figure, where = 12.00 A and /2 = 16.80 A. 30 V P2 P3 P4 P5 || = I₁ || P₁ W ==== W W 10 V W + P₂ + 20 V The power absorbed by each of the elements is as follows: P1 = W 12 1 P3 8 V P4 12 V 0.4/₁ + P5 0.4/1

Note: Please write the solution manually. H.W/Prove that the maximum efficiency occurs when the iron losses are equal to the copper losses (Pir=Pcu) It should only be when deriving the variable (I2) The rest of the values ​​are constant
