a. Increasing the value of the capacitor
b. Increasing the value of the resistor
c. Increasing the voltage from 15 to 20 volts

**Figure 4: Electrical Circuit Diagram**

This diagram represents an electrical circuit comprising several components connected in a particular arrangement. 

- **Components:**
  - **Ammeter (A):** Measures the current flowing through the circuit.
  - **R1:** A resistor with a resistance of 470 kΩ.
  - **R2:** Another resistor with a resistance of 10 kΩ.
  - **Variable Voltage Source (0 - 20 V):** Supplies voltage to the circuit.

- **Switch (AB):** A two-position switch with positions A and B, allowing for control of the circuit's operation.

- **Capacitor (C):** A component that stores electrical energy.

- **Ground:** The symbol representing a connection to the earth or a common return path for electric current.

**Circuit Operation:**
The switch can be toggled between positions A and B to control the flow of current through the resistors and capacitor. When the switch is in position A, the circuit likely initiates the charging process of the capacitor C. Switching to position B could alter the path of current, possibly initiating the discharging process of the capacitor.

**Educational Focus:**
The diagram helps explain the principles of electrical circuits, focusing on the role of components like resistors and capacitors in controlling current flow and storage of electrical energy. It also highlights the function of a switch in managing circuit operation.

**Blank for Student Completion:**
The circuit diagram includes a prompt: "…for the capacitor to reach full charge when the switch is… _____." This space is intended for students to fill in, encouraging them to think about the circuit's operation and when the capacitor reaches full charge.
