Question

An electrode connected to the negative terminal of a voltage source is called the anode.

• A. True
• B. False

Answer 1

The correct option is B False

• In 1879, British chemist William Crookes invented the Crookes tube, which is an experimental tube with a partial vacuum.
• He inserted 2 metal plates on each end of the tube. These metal plates are known as electrodes.
• The electrode connected to the negative terminal of the voltage source is called the cathode.
• The electrode connected to the positive terminal of the voltage source is called the anode.

Thus, the given statement is false i.e.,An electrode connected to the negative terminal of a voltage source is called the anode.
