це дослідження 1 та 2 та саме завдання

Let's solve the problem based on the provided images from experiments 1 and 2, as well as the task in question.

### From the images:
- **Experiment 1 (Дослід 1)**: You are measuring the current \( I_2 \) between a switch and a second lamp. The current \( I_2 = 0.2 \, \text{A} \) based on the answer you selected.
  
- **Experiment 2 (Дослід 2)**: You are measuring the voltage \( U_2 \) across the second lamp. The voltage \( U_2 = 1.6 \, \text{V} \), which corresponds to the answer you selected.

### Task:
You are asked to find the resistance \( R_2 \) of the second lamp using the formula:
\[
R_2 = \frac{U_2}{I_2}
\]

### Given values:
- \( U_2 = 1.6 \, \text{V} \)
- \( I_2 = 0.2 \, \text{A} \)

### Calculation:
\[
R_2 = \frac{1.6 \, \text{V}}{0.2 \, \text{A}} = 8 \, \Omega
\]

So, the resistance \( R_2 \) of the second lamp is **8 Ω**.

Let me know if you want any further details, and here are five related questions you can explore:
1. How would the resistance change if the voltage \( U_2 \) was doubled?
2. What happens to the current if the resistance increases while keeping voltage constant?
3. How do you measure resistance in a circuit with a voltmeter and ammeter?
4. Why do light bulbs have resistance, and how does it affect their brightness?
5. What is the difference between measuring voltage and current in a series circuit?

**Tip:** To find resistance in any circuit, use Ohm's Law: \( R = \frac{U}{I} \). Make sure you always have the voltage and current measured across the same component.
