An anode is an electrode through which electric current flows into a device. In a diode, for example, the anode is the electrode that receives the majority of the current. In a cathode ray tube (CRT), the anode is the positively charged electrode that accelerates the electrons being emitted from the cathode. What is anode or cathode? An anode is the electrode at which oxidation occurs in an electrolytic cell. A cathode is the electrode at which reduction occurs in an electrolytic cell. What is an anode in simple terms? An anode is an electrode through which current flows into a device. Does anode mean negative? No, anode does not mean negative. In fact, the anode is the positive terminal of a device, and the cathode is the negative terminal.
Why is the cathode negative?
The cathode of an electronic device is the terminal or electrode through which the negative charge carriers, electrons, flow out of the device. The word "cathode" comes from the Greek word "kathodos", which means "downward-going".
The cathode of a device is typically connected to the negative terminal of a power supply, which provides the electrons that flow into the device. In a diode, for example, the cathode is the negative terminal of the power supply, and the anode is the positive terminal.
The reason that the cathode is negative is because electrons are negatively charged particles, and they flow from the negative terminal to the positive terminal. Why anode is negative in battery? The anode of a battery is the electrode at which oxidation occurs. In other words, it is the electrode at which electrons are donated. Oxidation is a chemical reaction in which electrons are lost. The anode is therefore the negative electrode.
