, C. Transformer
Transformers do not use direct current (DC). Transformers work on alternating
current (AC), which is electrical current that flows in a single direction. A
transformer's principle is based on electromagnetic induction, which requires a
voltage source that changes with time. A DC supply is unidirectional, so the
transformer cannot work. If the input terminals of a transformer are connected to a
DC voltage, the transformer usually burns.
D. Nichrome. Most heating elements use Nichrome 80/20, which is 80%
nickel and 20% chromium. Nichrome is ideal because it has high resistance
and forms a chromium oxide layer when heated for the first time.
an electronic circuit that is capable of detecting very small changes in current flow
via changes in resistance from the heat released from the actual combustion of
flammable/combustible.
