    LED Resistor Calculation Formula - LED Series Resistor equations:

    Resistance Formula:

    R = Vs - (Vf × N)If

    For Example, Supply Voltage Vs = 9V , LED forward voltage Vf = 2.2V and Led forward current If = 20mA or 0.02A.

    R = 9V - (2.2V × 1)0.02A or, R = 340 Ω

    Power dissipated in a single LED Formula:

    P = Vf × If

    For Example, Supply Voltage Vs = 9V , LED forward voltage Vf = 2.2V and Led forward current If = 20mA or 0.02A.

    P = 2.2 × 0.02 or, P = 0.044W

    Power dissipated in all LEDs total Formula:

    P = N × Vf × If

    For Example, Supply Voltage Vs = 9V , LED forward voltage Vf = 2.2V and Led forward current If = 20mA or 0.02A.

    P = 1 × 2.2 × 0.02 or, P = 0.044W

    Power dissipated in the resistor Formula:

    PR = (If)2 × R

    For Example, Supply Voltage Vs = 9V , LED forward voltage Vf = 2.2V , Led forward current If = 20mA or 0.02A and Resistor = 340 Ω

    PR = (0.02)2 × 340 Ω or, PR = 0.136W
