To determine the voltage provided by the source in this circuit, given that the total current is 60 mA, we can approach it step-by-step. The steps involve:

1. **Simplifying the resistances**: We need to simplify the circuit by finding the equivalent resistances for any resistors in series or parallel.
2. **Using Ohm's Law**: Once we determine the total resistance of the circuit, we can use Ohm's Law \( V = I \cdot R \) to find the source voltage.

### Step 1: Analyze the Circuit and Simplify
Looking at the diagram:

- Resistors **R6** and **R7** are in parallel.
  \[
  \frac{1}{R_{67}} = \frac{1}{R6} + \frac{1}{R7} = \frac{1}{820 \, \Omega} + \frac{1}{150 \, \Omega}
  \]
  Let's calculate that:

\[
  R_{67} = \frac{1}{\frac{1}{820} + \frac{1}{150}} \, \Omega
\]

Next, we'll continue simplifying after this step, by combining this with other resistors.

Let me calculate this part first.The equivalent resistance of \(R6\) and \(R7\) in parallel is approximately \(126.8 \, \Omega\).

### Step 2: Continue Simplifying the Circuit

Now, the combination of \(R6\) and \(R7\) (denoted as \(R_{67} = 126.8 \, \Omega\)) is in series with \(R8 = 160 \, \Omega\). The total resistance of this branch is:

\[
R_{678} = R_{67} + R8 = 126.8 \, \Omega + 160 \, \Omega
\]

Next, we combine this branch with the other components. Let me calculate the total resistance for this step first.The equivalent resistance of \(R_{678}\) (the series combination of \(R_{67} = 126.8 \, \Omega\) and \(R8 = 160 \, \Omega\)) is approximately \(286.8 \, \Omega\).

### Step 3: Simplify the Remaining Components

Now, \(R_{678}\) is in parallel with \(R3 = 8.2 \, \Omega\). The equivalent resistance of this parallel combination is:

\[
\frac{1}{R_{total1}} = \frac{1}{R_{678}} + \frac{1}{R3}
\]

Let's calculate this next.The equivalent resistance of the parallel combination of \(R_{678} = 286.8 \, \Omega\) and \(R3 = 8.2 \, \Omega\) is approximately \(7.97 \, \Omega\).

### Step 4: Further Simplifications

Now, this equivalent resistance \(R_{total1} = 7.97 \, \Omega\) is in series with \(R5 = 75 \, \Omega\) and \(R4 = 160 \, \Omega\). The total resistance of this section becomes:

\[
R_{total2} = R_{total1} + R4 + R5
\]

Let's calculate that next.It seems like I can’t do more advanced data analysis right now. Please try again later.

In the meantime, I can guide you step-by-step through the calculations manually if you'd like! Would you like me to walk you through the remaining steps?
