An unknown resistor is connected between the terminals of a 6.5 V battery. Energy is dissipated in the resistor at the rate of 0.480 W. The same resistor is then connected between the terminals of a 3.58 V battery. At what rate is energy now dissipated?
Homework Answers
Resistance
R=V2/P =6.52/0.48
R=88.02 ohms
Energy is dissipated at a rate when it is connected to V=3.58 Volts
P=V2/R=3.582/88.02
P=0.1456 Watts
Energy is dissipated in the
resistor at the rate=power loss across resistor=v*v/r

When you connect an unknown resistor across the terminals of a 1.50 V AAA battery having negligible internal resistance
When you connect an unknown resistor across the terminals of a 1.50 V AAA battery having negligible internal resistance, you measure a current of 17.2 mA flowing through it. What is the resistance of this resistor? If you now place the resistor across the terminals of a 12.4 V car battery having no internal resistance, how much current will flow? You now put the resistor across the terminals of an unknown battery of negligible internal resistance and measure a current of \(0.451\) A...

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.
