i and iii
ii and iii
i,ii and iii

please answer me CORRECTLY will be able to get 50 points

those who answer correctly will be marked as a brillanist because I know the ans...​

Answer 1

JOULES LAW OF HEATING

H = I²Rt

where,

I - Current

R - Resistance

t - Time

Therefore , Heat produced by a conductor depends on CURRENT , RESISTANCE AND TIME .

Therefore , Option II AND III is correct.

Answer 2

Answer:

i and ii

i) The material of the conductor

ii) The current flowing through the conductor
