The image is a circuit diagram of a voltage regulator. It consists of two resistors, one on the left side and one in the center. The resistors are connected by a voltage source, which is represented by a red circle. 

On the right side of the diagram, there are two capacitors, one labeled "El condensador" and the other labeled "Vh". The capacitors are connected to the voltage source via a series of wires. The voltage source is labeled "1" and has a voltage of 1.5 ohms.

There are also two other resistors labeled "A" and "B" connected in the diagram. The first resistor is labeled as "VH" and is connected to a voltage voltage source. The second resistor is labelled as "2.2 ohms".

The diagram also includes a circuit equation, which shows the voltage of the circuit. The equation is written in black text on a white background. The diagram appears to be a mathematical equation that is used to calculate the voltage and current in a circuit.
