Hi,
I am stuck on a problem. I'm basically back as a beginner - years and years ago I thought I got this stuff... Apparently not, so I need an expert.
I've got a battery pack connected to a breadboard. I've cut the tops of safety to act as wires (desperate times ya know). They work on the voltmeter.
Through the breadboard they are connected by:
Battery pack -> safety pins -> resister -> LED -> to safety pin -> Battery pack.
I have two LED's in parallel two check if the diode direction makes a difference. Then I have the whole circuit again in parallel but changed the resistor to be after the LED's rather than before, to see if that makes a difference.
I just want one of the LED's to light up. I have slotted all the components into the right slots and the batteries have been changed with ones that I know work. Also all the components, including the battery pack and the breadboard are new. So I am puzzled as to why the LED won't light up.
The voltage just from the battery pack is 8V. The resistor is 1kΩ.
I don't know what to do or search for. Please help. Thank you in advance.
