Question

The provided image shows an electrical circuit diagram. Assuming the question is to find the total current drawn from the battery, the solution is as follows:

• A. The total current drawn from the battery is $\frac{25}{7} A$.
• B. The total current drawn from the battery is $\frac{20}{5.6} A$.
• C. The total current drawn from the battery is $5.6 A$.
• D. The total current drawn from the battery is $4 A$.

Answer 1

Answer: (A)

The total current drawn from the battery is $\frac{25}{7} A$.

Answer 2

1. Calculate the equivalent resistance of the parallel combination of $8\Omega$ and $2\Omega$: $R_p = \frac{8\Omega \times 2\Omega}{8\Omega + 2\Omega} = 1.6\Omega$.
2. Calculate the total equivalent resistance of the circuit: $R_{eq} = 4\Omega + 1.6\Omega = 5.6\Omega$.
3. Calculate the total current using Ohm's Law: $I = \frac{V}{R_{eq}} = \frac{20V}{5.6\Omega} = \frac{25}{7} A$.
