Which of the following has comparatively high electrical resistance and is used in the circuit to reduce current?

Correct option is A

The correct answer is (a) Resistor.
· A resistor is an electrical component that has comparatively high electrical resistance and is specifically designed to reduce current flow and adjust signal levels within circuits.
· Resistors are used in various applications to limit the amount of current that can flow through a circuit, protect components from damage due to excessive current, and divide voltages.
· The resistance value of a resistor is measured in ohms (Ω), and it follows Ohm's Law, which states that the voltage (V) across a resistor is equal to the current (I) flowing through it times its resistance (R): V=IR
Information Booster:
· Semiconductor: Materials with electrical conductivity between that of a conductor and an insulator. Semiconductors are used in electronic devices like diodes, transistors, and integrated circuits.
· Insulator: Materials with very high electrical resistance, used to prevent the flow of electric current. Insulators are used to protect and isolate electrical conductors.
· Conductor: Materials with low electrical resistance that allow the easy flow of electric current. Conductors, such as copper and aluminum, are used to make electrical wires and components.
