In the circuit shown inFigure P3.72, with the load resistor removed so thatthe current is zero (i.e., no load), the terminal voltageof the source is measured and is 20 V. Then, withRL = 2.7 kΩ, the terminal voltage is again measuredand is now 18 V. Determine the internal resistance andthe voltage of the ideal source.arrow_forward
- Use mesh current analysis to find the current i inthe circuit of Figure P3.27. Let V = 5.6 V; R1 = 50Ω ;R2 = 1.2 kΩ; R3 = 330 ; gm = 0.2 S; R4 = 440 Ω.arrow_forward1. In a circuit that contains only resistors in series, the current is the same throughout the circuit (remember that current is conserved!). The amount of current in the circuit is determined by the potential difference (or em f) of the battery and the equivalent resistance, Req, of the circuit. We can therefore write Ohm's Law as DeltaV = IReq. Assume the batteries supply a potential difference of DeltaV = 3.0 V, and use the currents measured in circuits 3a, 3b, and 3c to determine the equivalent resistance in each circuit. Please show the calculation of each. R1 = 150 ohm, R2 = 230 ohm R3 = 270 ohms (don't believe question should need these but providing anyways) Current MeasuredCurrent through R1 in 3a (Only resistor 1) Ir1= 0.01 amp Current through R1 in 3b (Resistor 1 and 2) Ir1= 0.0032 amp Current through R1 in 3c (Resistor 1, 2 and 3) Ir1 = 0.002 amparrow_forwardcan someone show me step by step how to do this problem and explain the concepts A device, shown in Figure P3.5a, can be modeled by a current source in parallel with a resistance. The relationship between the current through the device, iX, and the voltage across the device, vX, is given in the plot in Figure P3.5b. a) Find a model for the device that would be valid when current is in the range 1[mA] < iX < 5[mA]. This model must have numerical values for the current and resistance, and the polarities with respect to vX and iX should be shown in a diagram. b) A voltage source is applied across the device so that vX = 10[V]. Find the power delivered by the device in this situation.arrow_forward
