### Understanding Circuit Diagrams and Calculating Current

**Figure 16-1**

Three circuit diagrams are presented to illustrate different scenarios involving resistors and diodes. Below we explain each diagram in detail:

#### Diagram (a)

- **Components:**
  - A voltage source of 20 V
  - A resistor \(R_1\) with a resistance of 500 Ω
  - A silicon diode

- **Description:**
  The circuit shows a power source connected in series with a resistor \(R_1\) of 500 Ω and a silicon diode.

#### Diagram (b)

- **Components:**
  - A voltage source of 1 V
  - A resistor \(R_1\) with a resistance of 500 Ω
  - A silicon diode

- **Description:**
  This circuit is similar to (a) but with a voltage source of 1 V instead of 20 V.

#### Diagram (c)

- **Components:**
  - A voltage source of 50 V
  - A resistor \(R_1\) with a resistance of 1 kΩ (1000 Ω)
  - Another resistor \(R_2\) with a resistance of 1 kΩ (1000 Ω)
  - A silicon diode

- **Description:**
  In this circuit, a 50 V source powers a configuration with two resistors \(R_1\) and \(R_2\), both of 1 kΩ. The resistors are parallel to each other, separated by a silicon diode which is in parallel with \(R_2\).

#### Current Calculation Question

The task involves determining the current through the resistor in Figure 16-1(a).

**Question:**
If the diode is silicon, what is the current through the resistor in Figure 16-1(a)?

**Options:**
- 9.65 mA
- 25.9 mA
- 38.6 mA
- 40.0 mA
