What are the expected readings of the ammeter and voltmeter for the circuit in the figure below? (R = 8.60 Ω, ΔV = 5.30 V) Please refer to the image posted for the problem. Thanks

ammeter     I =  A
voltmeter     V =  V
Consider the following figure. (Assume \( R_1 = 5.40 \, \Omega, R_2 = 5.50 \, \Omega, \) and \( \mathcal{E} = 16.0 \, \text{V.} \)

**Circuit Diagram:**
- The circuit consists of two resistors \( R_1 \) and \( R_2 \), a 4.00 V battery, and a voltage source \( \mathcal{E} = 16.0 \, \text{V} \).
- \( R_1 \) is placed parallel to a 4.00 V battery.
- \( R_2 \) is connected in series with \( R_1 \).
- The combination is connected in series to an additional resistor of \( 10.0 \, \Omega \).
- The points labeled \( a \) and \( b \) are on either side of the \( 10.0 \, \Omega \) resistor.

**Tasks:**
(a) Calculate the magnitude of the potential difference between points \( a \) and \( b \) in the figure above.
\[ \_\_\_\_\_\_ \, \text{V} \]

(b) Identify which point is at the higher potential.
- \( \circ \) point \( a \)
- \( \circ \) point \( b \)
- \( \circ \) they are at equal potentials

**Instructions for Calculation:**
- Use the relevant laws (e.g., Ohm’s Law, Kirchhoff’s Laws) to determine voltages and currents.
- Consider the effects of resistors and internal voltage sources to find the potential difference.
