Question

In devices like electric iron the process of temperature regulation is done by-
(a) Fuse wire.
(b) Conducting wire.
(c) Bimetallic strip.
(d) Circuit breaker.​

Answer 1

Answer:

D circuit breaker is the correct option

Answer 2

The correct response to the given question is option c: Bimetallic strip.

• To avoid harm, it is critical to managing the temperature of electrical appliances and the settings in which they are used.
• The principle of heat conduction is employed in the case of an electric iron used to iron or press garments.
• However, due to the constant electrical supply, the temperature can rise to dangerous levels, causing harm to both the clothes and the gadget.
• As a result, a thermostat has been built inside it.
• The thermostat in this electrical gadget is a bimetallic wire that regulates the heat and flow of electricity.
• It maintains physical contact with the contact spring when the temperature is mild.
• However, when the temperature rises above a particular limit for iron, the strip expands.
• This bends the strip's structure, causing it to lose physical contact with the contact spring.
• As a result, the circuit is open and current flow is interrupted.
• In this way, the bimatellic strip serves as a thermostat in an electric iron.
