$\text { Figure } 6 \text { '1 }$ -If V_S=25 V, R₁=10 $\mathrm { k } \Omega$, R₂=15 $k \Omega$ and R₃=50 $\mathrm { k } \Omega$ in Figure 6-1 , I_T equals_______ A) 1.16 mA B) 1.58 mA C) 2.17 mA D) 2.5 mA

Question

Quizplus · Accepted Answer

The total resistance $ R_T $ is the sum of $ R_1 $, $ R_2 $, and $ R_3 $ since they are in series: $ R_T = 10k + 15k + 50k = 75k \Omega $. The total current $ I_T $ is given by $ I_T = \frac{V_S}{R_T} = \frac{25V}{75k \Omega} = 0.333 mA $. However, none of the options match this calculation, indicating a possible error in the problem setup or options.
