Answer:
(c) increase by a factor of four
Explanation:
the formular for the relationship between energy and current is E= I²Rt (Heat energy)
the heater is fairly independent of its temperature , and given the time to be constant.
with the current being doubled,
E = I² Rt
E/ I² = K
=
E2 =
I2 = 2* I1
E2 = E1 * 4*I1² / I1²
dividing , we have that E2 = 4 * E1
which means during the same time interval the amount of energy will increase by a factor of four.
