i am arranging 30-40 leds for a project
so parallel connections between them is the obvious choice
i am using 1.8V 20mA LEDs
and power supply is through AC to 1.5V-12V DC adapter
the circuit looks like railway tracks
|--------|----------|-----------|-----------|-----..(more LEDs in between)...|----positive terminal of battery
|--------|----------|-----------|-----------|-----..(more LEDs in between)...|----negative terminal of battery
where
| are LEDs
|
and -------- is single stranded copper wire
so if i supply 1.5V with all LEDs in parallel, will i need to connect resistors?Also what about resistance of single stranded wire?
i need to make quick connections as i have to make many such linear one dimesional arrays, so i am looking forward to not to connect any resistors.
please help me with selecting proper voltage value and proper circuit connections
