A resistor R and another resistor 2.00 R are connected in series across a battery.
If heat is produced at a rate of 18.0 W in R, then in 2.00 R it is produced at a rate of
a) 72.0 W
b) 36.0 W
c) 18.0 W
d) 9.00 W .
Homework Answers
in series same current flows
for resistor R, power = I2R =18 W
for 2R resistor, power = I2(2R) = 2 I2R = 2 x 18 = 36 W
so, (b) is correct

In circuit A, a resistor of resistance R is connected across the terminals of a battery with no internal resistance. In circuit B, an identical resistor is connected across a battery which is identical to the battery in the other circuit, except it has internal resistance r. 75.0% less power is dissipated in the resistor in circuit B than the resistor in circuit A. Determine the ratio r/R. Remember to express the answer with three significant digits.
