Answer 1

Answer:

1. only on voltage
2. fuse wire
3. 6

Please add my answer to brain list.

Answer 2

Answer:

A, both voltage and resistance

B,heater elements

C,6

Explanation:

A, Because voltage and resistance maintains the flow of current

B, Because it heats up quickly into a high temperature

C, because 1.5v × 6 = 9v
