• Forward Current: 20mA

• D2: Connects to resistor R8 with a resistance of 2kΩ.
• D5: Connects to resistor R2 with a resistance of 1.5kΩ.

• Source Voltage (V_{source}): Let's use +3V3 net
• Forward Voltage (V_{LED}): 2.0V
• Resistor (R): 2kΩ (R8)

• Source Voltage (V_{source}): Let's use +3V3 net
• Forward Voltage (V_{LED}): 2.2V (assuming 2.0-2.4V range)
• Resistor (R): 1.5kΩ (R2)

• Current through D2: 0.65mA (compared to the required 20mA)
• Current through D5: 0.73mA (compared to the required 20mA)

• D2 is unlikely to light up visibly because the current through it (0.65mA) is much lower than the required 20mA.
• D5 is also unlikely to light up visibly because the current through it (0.73mA) is much lower than the required 20mA.

• Forward Voltage ($V_F$): Not available in the provided excerpts. Standard green LEDs typically have a forward voltage of around 2.0V (assumption).

• Forward Voltage ($V_F$): 2.0V (typical) [1], [2], [3]
• Forward Current ($I_F$): 20mA (typical)

• Resistance: 1.5kΩ

• Connection for D2:
  • Connect D2:P1 (anode) to the power supply (net CHRG)
  • Connect D2:P2 (cathode) to one end of the resistor
  • Connect the other end of the resistor to ground
• Connection for D5:
  • Connect D5:P1 (anode) to the power supply (net CHARG)
  • Connect D5:P2 (cathode) to one end of the resistor
  • Connect the other end of the resistor to ground

• $V_{supply}$ is the voltage from the power supply
• $V_F$ is the forward voltage of the LED
• $R$ is the resistance of the current-limiting resistor

• $V_F = 2.0V$
• $R = 1.5k\Omega$

• $V_F = 2.0V$
• $R = 1.5k\Omega$

• The current through each LED (D2 and D5) is calculated to be 2mA.
• The typical forward current specified for D5 is 20mA (the same assumption would apply to D2 since they are both standard LEDs).

• D2 (Green LED) will light up but dimly (assuming a typical forward current should be around 20mA).
• D5 (Red LED) will light up but dimly as well, needing a current closer to 20mA for full brightness.

• Neither D2 nor D5 are expected to light up at full brightness given the current-limiting resistor value of 1.5kΩ. Replacing this resistor with a lower value (e.g., 150Ω) would allow for higher currents closer to the desired 20mA.

1. Obtain the parameters necessary for calculating the current through D2:
   • Designator: D2
   • Part Number: NCD0603C1
   • Forward Voltage ($V_F$): 2.0 V (assumption as there's no datasheet excerpt provided)
   • Forward Current: 20 mA (assumption as there's no datasheet excerpt provided)
2. Obtain the parameters necessary for calculating the current through D5:
   • Designator: D5
   • Part Number: NCD0603R1
   • Forward Voltage ($V_F$): 2.0 V
   • Forward Current: 20 mA
3. Retrieve the value of the current limiting resistor:
   • For D2:
     • Resistor: R2
     • Resistance: 1.5 kΩ
   • For D5:
     • Resistor: R2
     • Resistance: 1.5 kΩ
4. Calculate the current through the LEDs:
   The current through each LED can be calculated using Ohm's Law. The voltage drop across the resistor combined with the forward voltage of the LED gives the total voltage applied.
   Given:
   • Supply Voltage ($V_{CC}$): 3.3 V
   • Forward Voltage of LED ($V_F$): 2.0 V (for both D2 and D5)
   • Resistor Value ($R$): 1.5 kΩ
   Formula:
   $$I = \frac{V_{CC} - V_F}{R}$$
   Let's calculate the current using Python.

Python
# Parameters for D2 and D5 LEDs
V_CC = 3.3  # Supply Voltage in Volts
V_F_LED = 2.0  # Forward Voltage in Volts
resistor_value = 1500  # Resistor value in Ohms (1.5 kΩ)

# Calculate the current through the LEDs
current_through_led = (V_CC - V_F_LED) / resistor_value  # Current in Amperes
current_through_led_mA = current_through_led * 1000  # Convert to mA for better readability

current_through_led_mA

• Forward Voltage ($V_F$):
  • D2: 2.0 V (assumed, no specific data provided)

  • D5: 20 mA
• Current Limiting Resistor:
  • R2: 1.5 kΩ
• Calculated Current through LEDs:
  • $I = \frac{3.3V - 2.0V}{1.5k\Omega} \approx 0.87 \text{ mA}$
