Thermal runaway is a self destruction process in which an increase in temperature creates such a condition which in turn increases the temperature again. This uncontrolled rise in temperature causes the component to get damaged.

The resultant resistance for a pair of parallel resistances will be less than any one of the individual resistance.

Fire does not start with a current whose maximum value is less than 500 mA.

Constantan is a copper-nickel alloy also known as Eureka, Advance, and Ferry. It usually consists of 55% copper and 45% nickel. Its main feature is its resistivity, which is constant over a wide range of temperatures. Other alloys with similarly low-temperature coefficients are known, such as manganin

Aluminium and its alloys are good conductor of heat.

Antifreeze is used to prevent freezing of coolant in cold time.

Ripple factor of a rectifier measures the ripples or AC content in the output. It?s obtained by dividing AC rms output with DC output. For full wave bridge rectifier it is 0.482

Diodes are used to make rectifiers (full wave or half wave rectifiers are the most common examples), LED lamps uses diodes (diodes are generally doped for their use in this purpose) and logic gates can also be made using diodes using the fact that diodes are conducting only in the forward biased configuration.

All the statements are true for a diode.
