Anode is positive terminal and cathode is negative terminal.
Description : What is the difference between an anode and a cathode?
Answer : The anode is positively charged electrode and the cathode is negatively charged electrode.
Description : Do electrons flow from the anode to the cathode?
Answer : electrons flow from cathode to anode because the electron has a negative charge and repels from the negatively charged cathode whilst also attracting to the positively charged anode.
Description : Is the anode or cathode longer in LED ?
Answer : In LED anode terminal is longer and cathode terminal is smaller.
Description : Is an anode positive or negative?
