So this is my understanding, please tell me if it's correct. I graduated in BA and this is like the first time since middle school doing math
-----------------------------------------------------------
Here is my setup:
Tri-Cree Blue Green White
Blue Cree Part# XPEBBL-L1-0000-00301
45.7 Minimum Luminous Flux @ 350mA
Forward Voltage @1000mA = 3.47v
Green Cree Part# XPEBGR-L1-0000-00F01
122 Minimum Luminous Flux @ 350mA
Forward Voltage @1000mA = 3.58v
White Cree Part# XPEBWT-L1-0000-00F51
266 Minimum Luminous Flux @ 1000mA
Forward Voltage @1000mA = 3.15v
-----------------------------------------------------------
Blue:
Step 1: Resitance (ohms) = total voltage / current (amps)
-> R = (3.7-3.47)/1
-> R = 0.23
Step 2: Step 2: P (Watts) = R *( I^2)
-> P = 0.23*(1^2)
-> P = 0.23
Green:
Step 1: Resitance (ohms) = total voltage / current (amps)
-> R = (3.7-3.58)/1
-------------------
-> R = 0.12
===================
Step 2: Step 2: P (Watts) = R *( I^2)
-> P = 0.12*(1^2)
-------------------
-> P = 0.12
===================
And if I to use one resistor for a parallel Blue/Green I can just add their numbers up, am I correct?
R = 0.23 + 0.12 -> 0.35
P = 0.23 + 0.12 -> 0.35
This seems weird...now for the white
White:
Step 1: Resitance (ohms) = total voltage / current (amps)
-> R = (3.7-3.15)/1
-------------------
-> R = 0.55
===================
Step 2: Step 2: P (Watts) = R *( I^2)
-> P = 0.55*(1^2)
-------------------
-> P = 0.55
===================
Please comment on my calculation.
