Current can only flow through LEDs in one direction. It is important to connect the copper electrode (positive electrode) to the longer lead of the LED, and the zinc electrode (negative electrode) to the shorter lead. Your LED will never light up if it is connected backwards. write this as if you did this already rephrase as if you already did this
I have already connected the copper electrode (positive electrode) to the longer lead of the LED, and the zinc electrode (negative electrode) to the shorter lead. It was crucial to ensure the correct polarity to allow current flow through the LED. The LED is now successfully lighting up, confirming the correct connection.
