- a) Calculate the currents I1, I2 and I3 indicated in the figure. b) Explain Kirchhoff's law of meshes applied to solve the previous subsection and how Would Kirchhoff's law of nodes apply? (no need to solve for Kirchhoff's law of nodes) c) What is the potential difference (observe the signs) between the points a & e (Vae)? d) Discuss the law of conservation of energy and verify it with the data of your exercise.arrow_forwardIn the circuit, V1=128 V, R1=6 Ohm, the current through R1 flowing from left to right, iR1 = 6 A.Find the potential of the node "1" (Unit: V)arrow_forwardR1 = 1 kohms R2 = 1.4 kohms R3 = 6.8 kohms E = 8VD1: Si, rB = 2 ohms, rR = 215 kohms D2: Si, rB = 7 ohms, rR = 590 kohmsApplying second approximations, determine: a) Current through D1 b) Voltage across D_2 c) Voltage across R_3arrow_forward
- Assume that a 20 V voltage drop occurs across an element fromterminal 2 to terminal 1 and that a current of 4 A enters terminal 2.1. Specify the values of v and i for the polarity references shown inFig. 1.6(a)–(d).2. Calculate the power associated with the circuit element.3. Is the circuit element absorbing or delivering power?arrow_forwardWhen a car has a dead battery, it can often be started by connectingthe battery from another car across its terminals. The positive terminalsare connected together as are the negative terminals. The connection isillustrated in P1.12. Assume the current i in P1.12 is measuredand found to be 40 A.1. a) Which car has the dead battery?2. b) If this connection is maintained for 1.5 min, how much energy istransferred to the dead battery?arrow_forwardGiven:Vb = 100 voltsR = 10000 ohmsC = 200 μFAssuming that after a long period of time, the switch is flipped from position "A" to position "B" at t=0. Determine the current in the source-free circuit after 1 second.arrow_forward
- Energy Conservation Principle 4. Which components’ powers are negative? What’s the meaning of negative power? Which components’ powers are positive? What’s the meaning of positive power? **please type it using keyboard NO handwriting**arrow_forwardSubject: Circuits 1show your step by step solution pleasearrow_forwardConsider the circuit shown in Figure P1.36. a. Which elements are in series ? b. What is the relationship between i d and i c ? c. Given that i a = 3 A and i c = 1 A, determine the values of i b and i d.arrow_forward
- Question: The current flowing into a circuit element is given by i(t) = 5sin(2pi10t)mA for t >= 0. Find the charge flowing into the device for t >= 0. Also find the total charge entered into the device at t = 0.05s. My Comments: I just don't understand this at all. Can you explain it what it means?arrow_forwardCOURSE: HIGH VOLTAGE TECHNIQUE In an insulating environment consisting of insulating oil (Ɛr1=12.5) and porcelain (Ɛr2=2.5), the electric field enters the porcelain environment through the oil at an angle of 50 relative to the normal of the border surface. Since the field strength is 87 kV/cm in oil environment, calculate the electric field strength in the porcelain environment, the tangent and normal components of the electric field strength in both environments. PLEASE MAKE A DETAILED SOLUTION!arrow_forwardAfter a long time with the switch at position a, the switch moves to position b at time t=0. Assume that Vs = 22.7 V, R1 = 12 kΩ, R2 = 14 kΩ, R3 = 7 kΩ, and C = 194 nF. Calculate the voltage across the R2 resistor at time t=0.1ms. In this question, V = 22.7, R1 = 12kΩ, R2 = 14kΩ, R3 = 7kΩ and C = 194nF.arrow_forward
