Current Question (ID: 20211)

Question:

$\text{In the figure shown, what is the current (in Ampere) drawn from the battery? You are given}$ $R_1 = 15 \, \Omega, \ R_2 = 10 \, \Omega, \ R_3 = 20 \, \Omega, \ R_4 = 5 \, \Omega, \ R_5 = 25 \, \Omega, \ R_6 = 30 \, \Omega$

Options:

1. $\frac{7}{18}$
2. $\frac{20}{3}$
3. $\frac{9}{32}$
4. $\frac{13}{24}$

Solution:

$\text{Hint: } I = \frac{V}{R_{\text{eff}}}$ $i = \frac{15}{45 + \frac{25}{3}} = \frac{3}{9 + \frac{5}{3}} = \frac{9}{32}$
