I have a doubt about some numbers I'm getting in LiveWire... Can anybody explain origin of these values?

I believed that watts come from Amperes x Volts, but these ciphers are driving me crazy...

I get that

P = I * V

V = P / I (fixed)

V = 5.46 / 6.63

V = 0,8235 --- what is this number? It isn't V drop from de led, and is not V from batteries... What represents this number?

Thanks in advance!

It's possible that the value reflects led's resistance? I mean:

P = IV

V=P/I

V = 5.46mW / 6.63mA

V = 0,82V (V "efficiently" consumed by led)

1.5V - 0.82V = 0.676V (V "wasted" by led)

calculating resistance:

V = RI

R = V/I

R = 0.676V / 6.63 mA

R = 676mV / 6.63 mA

R = 101,96 Ohm

I't possible that nearly 102 ohm are the "resistance" coming from led? Or It's implicit in V drop from led, and I'm calculating it twice?

Note 1: I know there must be a resistor, it's only a way to simplify diagram.

Any advice will be very appreciated,

Thanks in advance!

**Note 2: The value I can't understand is 5.46 mW, I don't know what is its origin...**
