An electric heater is operated by applying a potential difference of 78.0 V across a nichrome wire of total resistance 7.00 Ω. a
aleksley [76]

PART A)

Here we know that

potential difference across the wire is

V = 78 volts

resistance of wire is

R = 7 ohm

now by ohm's law

V = iR

78 = i(7 ohm)

i = 11.14 A

Part b)

Power rating is defined as rate of electrical energy

it is defined as

P = iV

now we have

P = 11.14 ( 78)

P = 869.1 Watt

Which of the following properties must be known in order to calculate the amount of heat needed to melt 1.0 kg of ice at 0ºC?
meriva
If you're only melting ice ... turning solid ice at 0°C into liquid water at 0°C ...
then you only need to know t<span>he latent heat of fusion for water</span>. 

That's exactly what it means ... the amount of energy involved when a gram
of H₂O changes in either direction between liquid and solid, with no change
in temperature.
