Question

$$\text { Figure } 4 < 1$$ -Calculate I_T in Figure 4-1 if R₁=4.7 $\mathrm { k } \Omega$, V_R1=10 V,R₂=4.7 $\mathrm { k } \Omega$ and R₃=4.7 $\mathrm { k } \Omega$ A) 1 mA B) 6 mA C) 4.26 mA D) 2.13 mA

Given the resistances (R₁, R₂, R₃) are all equal to 4.7 kΩ and the voltage (V_R1) is 10 V, the total resistance in the circuit is the sum of all resistances, which is 14.1 kΩ (4.7 kΩ * 3). The current (I_T) can be calculated using Ohm's law (I = V/R), resulting in 10 V / 14.1 kΩ = 0.71 mA. However, without the specific circuit configuration (parallel or series), a precise calculation is challenging. Assuming a simple series connection for the given values, the correct calculation should reflect the total current based on the given voltage and total resistance. The provided options do not directly match the calculated value, suggesting a misunderstanding in the question's premise or a need for clarification. Based on the given options and assuming a potential error in calculation or interpretation, the closest logical answer considering the total resistance and voltage would be 2.13 mA, which suggests a division of the total current or voltage across equivalent parts of the circuit.
