Get started for freeAn idealized ammeter is connected to a battery as shown in Fig.
E25.28. Find (a) the reading of the ammeter, (b) the current through the
resistor, (c) the terminal voltage of the battery.
Fig. E25.28.
A resistor with resistance is connected to a battery that has emf 12.0 V and internal resistance . For what two values of will the power dissipated in the resistor be 80.0 W ?
A 5.00-A current runs through a 12-gauge copper wire (diameter
2.05 mm) and through a light bulb. Copper hasfree electrons per
cubic meter. (a) How many electrons pass through the light bulb each
second? (b) What is the current density in the wire? (c) At what speed does
a typical electron pass by any given point in the wire? (d) If you were to use
wire of twice the diameter, which of the above answers would change?
Would they increase or decrease?
In the circuit in Fig. E25.47, find (a) the rate of conversion of internal (chemical) energy to electrical energy within the battery; (b) the rate of dissipation of electrical energy in the battery; (c) the rate of dissipation of electrical energy in the external resistor.
In the circuit shown in Fig. E26.20, the rate at which R1 is dissipating electrical energy is 15.0 W. (a) Find R1 and R2. (b) What is the emf of the battery? (c) Find the current through both R2 and the 10.0 Ω resistor. (d) Calculate the total electrical power consumption in all the resistors and the electrical power delivered by the battery. Show that your results are consistent with conservation of energy.
