Will the LED in this circuit diagram glow?
No, because Positive terminal of the battery is connected to the negative terminal of LED
Yes, because negative terminal of the LED is connected to the negative terminal of USB
Yes, because P- terminal of the battery is connected to P-terminal of the LED and N- terminal of the battery is connected to the N-terminal of the LED!
No, because its an open circuit
This short circuit wire is proving as the_______________
longest path with maximum resistance so the current will flow through iy
shortest path with more resistance so the current will not flow through it
Longest path with less resistance so the current will not flow through it
shortest path without much resistance so the current will flow through it
