A resistor is an electrical component that limits or regulates the flow of electrical current in an electronic circuit. It is a passive two-terminal electrical component that implements electrical resistance as a circuit element. The main purpose of a resistor is to reduce the current flow and to lower the voltage in any particular portion of the circuit. Resistors are available in different shapes and sizes, and they might be static, standard resistor, special, or a pack of variable resistors. There are two basic types of resistors: linear and non-linear. Linear resistors have values that change with changes in applied temperature and voltage, while non-linear resistors have values that change according to the temperature and voltage applied and are not dependent on Ohm’s law. Fixed resistors are the most common type of resistors and have a specific value that cannot be changed. There are different types of fixed resistors, including carbon composition resistors, wire wound resistors, thin film resistors, and thick film resistors.

Class 10 is a level of education in India, and it is not clear from the search results what specifically is meant by "resistor class 10."
