  • The figure shows an L-R circuit the time constant for the circuit is

    A
    `L/2R`
    B
    `(2L)/R`
    C
    `(2R)/L`
    D
    `R/(2L)`

  • Assertion: The quantity L//R possesses dimensions of time. Reason: To reduce the rate of increases of current through a solenoide should increase the time constant (L//R) .

    A
    If both the assertion and reason are true and reason is a true explantion of the assertion.
    B
    If both the assertion and reason are true but the reason is not true the correct explantion of the assertion.
    C
    If the assertion is true but reason false
    D
    If both the assertion and reason are false.
