![**Image Transcription for Educational Website:**
**Problem Statement:**
(a) In the figure, what value must \( R \) have if the current in the circuit is to be 0.96 mA? Take \( \varepsilon_1 = 2.9 \, \text{V}, \varepsilon_2 = 4.7 \, \text{V}, \) and \( r_1 = r_2 = 3.4 \, \Omega. \)
(b) What is the rate at which thermal energy appears in \( R \)?
**Diagram Description:**
The circuit diagram consists of two batteries and three resistors.
- Battery 1 (\( \varepsilon_1 \)) has a voltage of 2.9 V and is connected in series with a resistor (\( r_1 = 3.4 \, \Omega \)).
- Battery 2 (\( \varepsilon_2 \)) has a voltage of 4.7 V and is connected in series with a resistor (\( r_2 = 3.4 \, \Omega \)).
- Resistor \( R \) is connected between the junctions formed by the two batteries and resistors \( r_1 \) and \( r_2 \).
**Input Fields:**
1. **(a) Required Value of \( R \):**
- Number: [Input Box]
- Units: [Dropdown]
2. **(b) Rate of Thermal Energy Appearance in \( R \):**
- Number: [Input Box]
