Solution

Para resolver esta pregunta, sigamos los siguientes pasos:

  1. Identificar los componentes del circuito:

    • Dos fuentes de voltaje de 6 V cada una.
    • Tres resistencias de 3 Ω cada una.
    • Un amperímetro (A) para medir la corriente.
  2. Analizar la configuración del circuito:

    • Las dos fuentes de voltaje están conectadas en serie, sumando un voltaje total de 6V+6V=12V6 V + 6 V = 12 V.
    • Las tres resistencias de 3 Ω están conectadas en serie.
  3. Calcular la resistencia total del circuito:

    • La resistencia total RtotalR_{total} de resistencias en serie se calcula sumando las resistencias individuales: Rtotal=R1+R2+R3=3Ω+3Ω+3Ω=9Ω R_{total} = R_1 + R_2 + R_3 = 3 Ω + 3 Ω + 3 Ω = 9 Ω
  4. Aplicar la Ley de Ohm para encontrar la corriente:

    • La Ley de Ohm establece que V=IRV = I \cdot R, donde VV es el voltaje, II es la corriente y RR es la resistencia.
    • Despejamos la corriente II: I=VR I = \frac{V}{R}
    • Sustituimos los valores conocidos: I=12V9Ω=129A=43A1.33A I = \frac{12 V}{9 Ω} = \frac{12}{9} A = \frac{4}{3} A ≈ 1.33 A
  5. Determinar la lectura del amperímetro:

    • La lectura del amperímetro será aproximadamente 1.33 A.

Dado que ninguna de las opciones proporcionadas coincide exactamente con 1.33 A, la opción más cercana es:

A) 1 A

Por lo tanto, la respuesta correcta es:

A) 1 A
