Voltmeter phone charger

I fitted this earlier, I’m very good at running out of charge with my phone when out on rides, it’ll also power the sat nav, so just been for a ride, running at approx 6k revs it’s 14.2v and doesn’t go above that so reg/rec is doing its job nicely, but I got a surprise when I switched the lights on, it read 14.4 and up to 14.6 but didn’t go above that, I know nothing about electronics, does switching the lights on employ another phase of the alternator or something?, Cheers Mark

I'm no electrical expert but is it something to do with Ohm's Law?

Ohm's law states that the electrical current (I) flowing in a circuit is proportional to the voltage (V) and inversely proportional to the resistance (R) i.e. I = V/R.

So, when you turn the lights on, you increase the current draw, which means the voltage also increases in proportion.

Happy to be corrected if I'm wrong!
