Let say I have non-inductive Load and it is rated as follow:
- 0.2A @ 1V applied
- 2A @ 5V applied
Which is powered by a DC battery and is rated as follow:
- 5V output
- 1A max current supply
I am going to divide the supply voltage by switching it with PWM, say 20% duty cycle and as a result we can simulate a 1V voltage is applying onto the Load. In this case, may I know how much current will the Load draw? As it is a non-inductive Load, does it mean that it would (tend to) draw 2A current for every high state in PWM (because high state is 5V)? However, the battery can provide only 1A at maximum, so it may not work properly.
OR... Should I just treat it as 1V applied and so that the current drawn by the Load should be only 0.2A?
