LED Biasing ⚫ LED max current for standard through-hole LEDs is ~20mA. Calculate R₁ for the circuit in Figure 15 assuming VLED=2.0V, ILED=20mA, Supply+=9.0V (In lab, we will use the first available resistor value larger than the calculated resistance to ensure ILED < 20mA). R₁= (9.0V) • Repeat the calculation of R₁ for the circuit in Figure 15 assuming VLED=3.0V, ILED=20mA, Supply+=9.0V (In lab, we will use the first available resistor value larger than the calculated resistance to ensure ILED< 20mA). R₁= (9.0V) Supply+ GND R1 LED Figure 15: Simple LED Blas Circuit
