1. Find the current I through a resistor of resistance R = 2 Ω if the voltage across the resistor is 6 V

2. A small light bulb is connected to a 6 V battery and draws 2 A of current. What is the net resistance of the bulb?

3. A motor with an operating resistance of 32 ¾ is connected to a voltage source. The current in the circuit is 1.5 A. What is the voltage of the source?

4. In the circuit below resistors R1 and R2 are in series and have resistances of 5 Ω and 10 Ω, respectively. The voltage across resistor R1 is equal to 4 V. Find the current passing through resistor R2 and the voltage across the same resistor

5. In the circuit below resistors R1 and R2 are in parallel and have resistances of 8 Ω and 4 Ω, respectively. The current passing through R1 is 0.2 A. Find the voltage across resistor R2 and the current passing through the same resistor.

6. Conectadas a la misma pila ¿Alumbran más dos bombillas en serie o una

sola?

7. ¿Qué relación hay entre la potencia de dos bombillas conectadas en serie y

la de dos bombillas conectadas en paralelo?

8. ¿Puede circular intensidad por un cable conectado a 0V?

9. ¿Se apaga una bombilla si abrimos el interruptor cuando éste está situado

después de la bombilla?

10. Can a wire carry a current and still be neutral—that is, have a total

charge of zero? Explain.

11. Car batteries are rated in ampere-hours (A⋅h). To what physical quantity

do ampere-hours correspond (voltage, charge, . . .), and what relationship

do ampere-hours have to energy content?

12. Why are two conducting paths from a voltage source to an electrical

device needed to operate the device?

13. Why isn’t a bird sitting on a high-voltage power line electrocuted?

Contrast this with the situation in which a large bird hits two wires

simultaneously with its wings.

14. Deduce las fórmulas de las resistencias equivalentes de dos

resistencias en serie y paralelo. Para ello calcula la intensidad por la pila

en ambos casos y calcula la resistencia que habrá que poner para que

circule la misma corriente. Repite luego los cálculos utilizando letras en

vez de números.
