### Example 1: Voltage Divider Circuit (Arduino)
In this example, we'll use two 2K Cermet resistors to create a voltage divider circuit to measure a voltage signal using an Arduino board.
```c
const int vin = 5;  // input voltage (5V)
const int r1 = 2000;  // 2K ohm resistor
const int r2 = 2000;  // 2K ohm resistor
int sensorPin = A0;  // analog input pin
void setup() {
  Serial.begin(9600);
}
void loop() {
  int sensorValue = analogRead(sensorPin);
  float voltage = (sensorValue  vin) / 1023.0;
  float vout = voltage  (r2 / (r1 + r2));
  Serial.print("Output voltage: ");
  Serial.println(vout);
  delay(1000);
}

In this example, we'll use a single 2K Cermet resistor to limit the current to an LED connected to a Raspberry Pi's GPIO pin.
```python
import RPi.GPIO as GPIO
# Set up GPIO pin for output
GPIO.setmode(GPIO.BCM)
GPIO.setup(17, GPIO.OUT)
# Set up LED and resistor
led_pin = 17
resistor_value = 2000  # 2K ohm resistor
led_voltage = 3.3  # voltage of the LED
try:
    while True:
        # Calculate the current through the LED
        current = led_voltage / resistor_value
        print("Current through LED: {:.2f} mA".format(current  1000))
        # Turn on the LED
        GPIO.output(led_pin, GPIO.HIGH)
        time.sleep(1)
        # Turn off the LED
        GPIO.output(led_pin, GPIO.LOW)
        time.sleep(1)
except KeyboardInterrupt:
    GPIO.cleanup()
