Question

In the image, two ideal batteries are shown within a circuit diagram. The batteries have electromotive forces (emfs) denoted as \( \mathcal{E}_1 = 4.00 \, \text{V} \) and \( \mathcal{E}_2 = 12.0 \, \text{V} \). There are three resistors in the circuit, each with a resistance of \( 2.4 \, \Omega \). The electrical potential is defined as zero at the grounded point of the circuit. The problem asks for the electrical potentials \( V(a) \) and \( V(b) \) at two specified points in the circuit.

The circuit diagram shows:

- A series connection of resistors labeled \( R_1 \), \( R_2 \), and \( R_3 \).
- Battery \( \mathcal{E}_1 \) is connected to \( R_1 \) and \( R_4 \), in parallel, and between these two resistors is a node labeled \( a \).
- Battery \( \mathcal{E}_2 \) is connected through \( R_3 \), with a node labeled \( b \) between \( R_2 \) and \( R_3 \).
- There are two nodes in the circuit marked where potentials need to be determined: point \( a \) and point \( b \).

The task involves applying principles of electrical circuits, such as Ohm’s Law and Kirchhoff’s Rules, to find the required potentials at points \( a \) and \( b \).
