    The direction of electric current is always opposite to

  • Question 2
    1 / -0.25

    A student carries out an experiment and plots the V-I graph of three samples of nichrome wire with resistances R1, R2 and R3 respectively. Which of the following is true?

  • Question 3
    1 / -0.25

    If 20 Coulombs of charge passes a point in a circuit in 1 second, what is the value of the current flowing?

  • Question 4
    1 / -0.25

    Choose the incorrect statement regarding ohm’s law.

  • Question 5

    Current carriers in a solid conductor are

  • Question 6
    1 / -0.25

    There is a current of 1.344 amp in a copper wire whose area of cross-section normal to the length of the wire is 1 mm2. If the number of free electrons per cm3 is 8.4 × 1022, then the drift velocity would be: 

  • Question 7
    1 / -0.25

    If electric current of 4 A is needed to operate a chemical plant, then find the electric charge flow through the wire in 3 seconds.

  • Question 8
    1 / -0.25

    The electron drift speed is small and the charge of the electron is also small but still, we obtain large current in a conductor. This is due to

  • Question 9
