Answer 2

Given: current is tripled, resistance and time is constant

To find: Heat generated in the conductor

Solution: we know that heat produced in a conducting wire can be calculated through the given formula:

H=I^2Rt

where H is heat generated in joules

I is current in the conductor

R is the resistance of the conductor

t time of current flow

we are given that time and resistance has kept constant

Therefore, we can say that H ∝ I^2

that is amount of heat produced in a conductor is directly proportional to the square of the amount of current flowing through the conductor.

H1/H2= (I1/I2)^2

where H1 and I1 are after the change in current

H1= H2(3I/I)^2= H2(9)

Therefore, we can say that heat generated will be increased by the factors of 9.
