  • Question 1
    1 / -0

    Given the time domain voltage v = 4 cos ((π/6)t). The expression for instantaneous power across an impedance z = 2 L60o is:

  • Question 2
    1 / -0

    The power consumed by a coil is 300 W when connected to a 20 V dc source and 175 W when connected to a 30 V ac source the reactance of the coil is – (in Ω)

  • Question 3
    1 / -0

    The voltage across the circuit and the current flows through it, are given by following expressions:

    V(t) = 10 – 5 sin (ωt + 60°) V

    i(t) = 5 + 10 sin (ωt) A

    Which of the following statement is/are true?
