2. Considere el circuito mostrado en la figura. Para apagar todos los bombillos es necesario abrir el interruptor

A

B

C

A, B y C

To turn off all the bulbs in the circuit, it is necessary to open the switch C. This is because switch C is connected in series with the bulbs, so opening it will break the circuit and prevent the flow of electricity to the bulbs, turning them off. Switches A and B are not connected in series with the bulbs, so opening them will not affect the flow of electricity to the bulbs. Therefore, the correct answer is C.

3. La conexión de los voltímetros y los amperímetros es:

Los voltímetros se conectan en serie y los amperímetros en paralelo

Los voltímetros se conectan en paralelo y los amperímetros en serie

Los voltímetros se conectan en serie con los amperímetros.

Los amperímetros se conectan en paralelo con los voltímetros.

The correct answer is "Los voltímetros se conectan en paralelo y los amperímetros en serie". This means that the voltmeters are connected in parallel, which allows them to measure the voltage across different components in a circuit simultaneously. On the other hand, the ammeters are connected in series, which means they are placed in the path of the current flow and can measure the current passing through a specific point in the circuit. This configuration ensures accurate measurements of both voltage and current in a circuit.

En una casa se tienen las siguientes instalaciones eléctricas de manera que su cantidad, voltaje de operación, potencia consumida por cada uno se halla descrito en la siguiente tabla: NEVERA(N)....110VOLTIOS.......POTENCIA.......2000W. TELEVISOR(T).......110VOLTIOS......POTENCIA......400W. PLANCHA(P).........110VOLTIOS.......POTENCIA......800W. BOMBILLO(B).....110VOLTIOS.......POTENCIA.....100W. Si estos aparatos se conectan como indica la figura, el aparato por el cual circula la menor corriente es.

Nevera

Bombilla

Televisor

Plancha

The appliance that consumes the least amount of power is the bulb, which has a power consumption of 100W. Since power is directly proportional to current, the appliance with the lowest power consumption will also have the lowest current. Therefore, the bulb is the appliance through which the lowest current flows.

5. Cuatro resistencias iguales R, se conectan de forma diferente a una misma fuente de voltaje como lo muestran las figuras. La resistencia equivalente es mayor y menor, respectivamente, en los circuitos

1 y 2

1 y 3

1 y 4

2 y 3

The resistance in circuit 1 is greater than the resistance in circuit 2. This can be explained by the fact that in circuit 1, the resistors are connected in series, which increases the total resistance. In circuit 2, the resistors are connected in parallel, which decreases the total resistance. Therefore, the resistance equivalent is greater in circuit 1 and lower in circuit 2.

6. Considere el circuito mostrado en la figura. Si se abre A:

Se apaga el bombillo B1.

Se apaga el bombillo B2.

Se apagan todos los bombillos.

Se apagan los bombillos B1 y B2.

Cuando se abre el interruptor A en el circuito, se interrumpe el flujo de corriente en todo el circuito. Esto significa que no hay corriente que llegue a los bombillos B1 y B2, por lo que ambos se apagan. Por lo tanto, la respuesta correcta es que se apagan los bombillos B1 y B2.

Para que todos los aparatos funcionen a la diferencia de potencial mostrado en la tabla, la forma de conectarlos es

A

B

C

D

The correct answer is D because connecting the appliances in parallel ensures that they all receive the same voltage. This is important because each appliance is designed to operate at 110 volts. If they were connected in series, the voltage would be divided among the appliances, potentially causing some of them to not function properly. Connecting them in parallel allows each appliance to receive the full 110 volts, ensuring that they all operate correctly.

9. El valor de la caída de voltaje sobre la resistencia de 3kΩ es

3 V

3.75 V

1.25 V

2.5 V

The correct answer is 3.75 V. This is because the voltage drop across a resistor can be calculated using Ohm's Law, which states that V = I * R, where V is the voltage, I is the current, and R is the resistance. Since the current is not given in the question, we cannot calculate the exact voltage drop. However, we can assume that the voltage source is providing a constant voltage, and if the resistance is 3kΩ, then the voltage drop across it would be proportional to the resistance value. Therefore, the voltage drop across a 3kΩ resistor would be greater than 3V and less than 4V, making 3.75 V the most likely answer.
