I was wondering if the following makes any difference, technically.
Say, some load is rated at 100 W at 230 Volts (resistive load assumed)
By using Power formula:
I=P/V [Power factor=1 assumed]
So, I=100/230 = 435 mA
Let's connect a 12 V source [battery] across this same load:
I=P/V
So, I=100/12 = 8.3 A
Hence, if a 40 Ah, 12 V battery is connected across this load, it would last for approximately 5 hours:
Total hours, h = Ah/A
h = 40 Ah/8.3 A
So, h = 4.8 hours
I know that this setup would require thicker connecting wires due to higher amperage, but I have the following doubts:
Is it practical?
Can a 230 V rated load be connected to a 12 V source?
What happens if the load were to be inductive/capacitive?
Please shoot your comments fellas!
