Which of the following heating element has the lowest operating temperature?

Kanthal
Graphite
Nichrome
Eureka

ANSWER EXPLANATION DOWNLOAD EXAMIANS APP

The melting point of Eureka is 1221 to 1300 °C
The melting point of Kanthal is 1,425 °C
The melting point of Nichrome is 1400 °C
The melting point of Graphite is 3,600°C
Hence Eureka has the least range of temperature.
