Exactly what it says on the tin. I have a Sound Blaster X-Fi Xtreme Audio Notebook sound card and I was measuring its output frequency using frequency counter connected to the card's output. Frequency was generated using a program called FrequencyGenerator.
This article contains information about Cathodic Protection. Cathodic Protection is an electrochemical means of corrosion control in which the oxidation reaction in a galvanic cell is concentrated at the anode and suppresses corrosion of the cathode in the same cell. Figure 1 shows a simple cathodic protection system.
1.1 The positively charged electrode of an electrical device, such as a primary cell, that supplies current. Example sentences. 1  Therefore, in electrolytic cells, the cathode is the negative terminal and the anode is the positive terminal.2  Most fuel cells use a polymer electrolyte membrane to separate the cathode and anode.xample sentences. 1  Therefore, in electrolytic cells, the cathode is the negative terminal and the anode is the positive terminal. 2  Most fuel cells use a polymer electrolyte membrane to separate the cathode and anode.
