Resistance Heating in Hot Surface Ignitor (HSI)

How does the HSI generate enough heat to ignite a flame?

The HSI uses what to produce enough heat to ignite a flame?

Answer:

The HSI utilizes resistance to generate the heat necessary for igniting a flame, similar to electric furnace coils that heat up due to the resistance they offer to the electrical current.

The HSI (Hot Surface Ignitor) uses resistance to produce enough heat to ignite a flame. In an electric furnace, the coils, when electric current passes through them, encounter resistance, which causes the coils to heat up.

This is because the electrical energy is being converted into thermal energy through the resistance offered by the material of the coils. This is similar to how a toaster or an electric stovetop works.

Capacitors, inductors, and ideal switches do not dissipate power in the same way and hence, they are not used in this context.
