Answer:
I know it looks long but it's just intimidating
Explanation:
this is just the heating effect of current nothing particular in general
they used nichrome wire because it is good conductor of electricity
in this activity we are actually just passing electricity in that wire and as we increase the number of batteries the current increases and hence the heat increases
just so you know h=i^2Rt
the reason behind this is that as the current increases the electron flow thought it increases it leads to more collision in the metal lattice and produce more heat
heat produced depends on square of current so if current increases heat increases
