It seems the image you provided didn’t load successfully, so I can’t see the specific problem details (like circuit diagrams, resistor values, battery voltage, etc.). Could you please describe the problem in text form? For example:

• Is it a circuit with resistors in series/parallel?
• What are the values of the resistors and battery voltage?
• What quantity do you need to calculate (current, voltage, equivalent resistance)?

Once you share these details, I can help solve the problem step by step.

If you had a specific circuit in mind (e.g., common problems like resistors in parallel then series), let’s assume an example to illustrate:
Example Problem: A 12V battery is connected to R₁=6Ω (parallel with R₂=12Ω), then in series with R₃=4Ω. Find total current and current through R₁.

Solution:

1. Equivalent resistance of R₁||R₂:
   ( R_{12} = \frac{R_1 R_2}{R_1 + R_2} = \frac{6×12}{6+12} = 4Ω )
2. Total resistance: ( R{total} = R{12} + R_3 = 4+4=8Ω )
3. Total current: ( I{total} = \frac{V}{R{total}} = \frac{12}{8}=1.5A )
4. Voltage across R₁||R₂: ( V{12}=I{total}×R_{12}=1.5×4=6V )
5. Current through R₁: ( I1 = \frac{V{12}}{R_1} = \frac{6}{6}=1A )

Let me know your actual problem details, and I’ll adjust the solution accordingly!
