A battery has an emf of ε=12.0V. Tee terminal voltage of the battery is V=11.6V when it is delivering P=20.0W of power to an external load resistor R.
(a)What is the value of R?
(b)What is the internal resistance r of the battery?
25.34 . When a resistor with resistance R is connected to a 1.50-V flashlight battery, the resistor consumes 0.0625 W of elec- trical power. (Throughout, assume that each battery has negligible internal resistance.) (a) What power does the resistor consume if it is connected to a 12.6-V car battery? Assume that remains constant when the power consumption changes. (b) The resistor is connected to a battery and consumes 5.00 W. What is the voltage of this battery?
A 2-Ω and a 6-Ω resistor are connected in series with a 24-V battery of internal resistance .5-Ω. What is the terminal voltage and the power lost to internal resistance?
