6.A resistor R1 dissipates power P when connected to a certain generator with
voltage V. If a resistance R2 is put in series with R1 the power dissipation by R1
A) Decreases
B) Increases
C) Remains the same
D) Any of the above depending upon the value of R1 and R2

  • electrical -

    R2 decreases the current. Therefore the
    power dissipated in Ri Decreases.

    P = I^2 * R1.
