I want a Christmas tree. Not the kind with pine needles but the kind you find in a submarine that tells you which hatches are open. With the beautiful weather we have been experiencing, our windows open during the day. The nights are a little to chilly. Of late, the heater has been turned on to combat the cold, but much to my chagrin, at least one window seems to remain open each night. If you have noticed slightly warmer days in Knoxville, you can thank my family and my elevated electric bill.
If I have a device that requests 6V input and I have an a/c adapter that outputs 9V, will the device draw only the 6V it needs or will it try to take all 9V and burn itself out? In this case the circuit is simply a light. It has the switch and the bulb with an optio of being powered by 4 AA batteries or 6V input. No amp requirement specified.
Watt’s it matter?
