16. A resistor R1 dissipates power P when connected to a
certain
generator. If a resistor R2 is added in series with R1, the
power
dissipated by R1 is
a. less than P.
b. greater than P.
c. P.
d. any of the above, depending on the values of R1 and R2
17. If the second resistance of the previous exercise is
connect in parallel with R1; then the power
dissipated by R1 is
a. less than P.
b. greater than P.
c. P.
d. any of the above, depending on the values of R1 and R2
