Question

In the circuit shown in the figure, each battery is delivering energy to the circuit by electrical transmission. All the resistors have equal resistance. (i) Rank the electric potentials at points a, b, c, d, e, f, g, and h from highest to lowest, noting any cases of equality in the ranking. (ii) Rank the magnitudes of the currents at the same points from greatest to least, noting any cases of equality.

### Circuit Diagram Explanation

This image represents a basic electrical circuit diagram involving two voltage sources and resistors.

- **Voltage Sources**: 
  - There is a 12V battery on the left side, connected between points \( a \) and \( g \).
  - A 9V battery is on the right side, connected between points \( d \) and \( h \).

- **Resistors**: 
  - A resistor is connected between points \( a \) and \( b \).
  - Another resistor is connected between points \( c \) and \( d \).
  - A third resistor is positioned between points \( e \) and \( f \), vertically bridging the two horizontal paths.

- **Connections**: 
  - The circuit forms a bridge with nodes at \( b \), \( c \), \( e \), \( f \), \( g \), and \( h \).
  - The path from \( b \) to \( e \) and from \( c \) to \( e \) allows current to pass through the middle resistor.
  - The ground is connected at \( g \) providing a common reference point for the circuit.

This setup might be used to demonstrate principles of circuits such as Kirchhoff's laws or the analysis of series and parallel resistors.
