- The voltage and power values for each of the elements shown in P1.30 are given in Table P1.30. Find the value of the current through each of the elements usingthe values of power and voltage and the current directions shown inthe figure.arrow_forwardThe current entering the upper terminal of a basic circuit element is i=20cos5000t A. Assuming the charge at the upper terminal is zero at the instant the current is passing through its maximum value. What is the expression for the charge q(t)?

A is 9 coulombs, B is 12 seconds, C is 3 volts, and D is 24 seconds. Give the current of this component at t1 = 8 sec. You must round your answer to the nearest thousandth and give your answer as an integer followed by the appropriate metric prefix and the letter that represents the units of current.arrow_forward

- Figure P1.27 shows an ammeter (AM) and voltmeter (VM) connected to measure thecurrent and voltage, respectively, for circuit element A. When current actually enters the + terminalof the ammeter, the reading is positive, and when current leaves the + terminalreading is negative. If the actual voltage polarity is positive at the + terminal of the VM, thereading is positive; otherwise, it is negative. (Actually, for the connection shown, the ammeterreads the sum of the current in element A and the very small current taken by the voltmeter. Forpurposes of this problem, assume that the current taken by the voltmeter is negligible.) Find thepower for element A and state whether energy is being delivered to element A or taken from it if a. the ammeter reading is +2 A and the voltmeter reading is +30 V.b. the ammeter reading is -2 A and the voltmeter reading is - 30 V.c. the ammeter reading is -2 A and the voltmeter reading is + 30 V.arrow_forwardFor the circuit shown in Figure P1.77, solve for the current i x. What types of sources are present in this circuit?arrow_forwardPlease answer the following points in detail and rigorously. Instead ofresort to formulas, develop from basic principles (laws ofvoltages and currents, definition of electrical power, properties ofphasors, among others) d) Show that the complex power consumed by two elements in parallel is the sum of the individual complex powers. After, repeat the procedure but for two elements in series. e) What meaning would you give to the P consumed by an element? Which to Q? f) Suppose you know P and Q for a two-terminal element. What is the power factor of this element? When would i be in early and when behind? g) Suppose you know the equivalent resistance R and the reactance X equivalent of a two-terminal passive network. What is the factor power of red bliss? When would I be in advance and when in backwardness?arrow_forward
