R2 determines the current. Calculations: - LED current is approximately equal to: 0.5 / R2 - R3 power: the power dissipated by the resistor is approximately: 0.25 / R2. choose a resistor value at least 2x the power calculated so the resistor does not get burning hot. so for 700mA LED current: R2 = 0.5…
