The current through the heater is 8 A if potential difference is increased to 120 V.
Explanation:
- According to Ohm's Law, the potential difference (Voltage) is directly proportional to the current flowing through a conductor.
That is, V ∝ I
⇒ V = IR where R is the constant of proportionality called resistance.
- In this case, given voltage = 60 V and current = 4 A. To find the current, first find the constant of proportionality, resistance of the heater.
R = V/I = 60/4 = 15 ohm
- If the potential difference is increased to 120 V, find the current flowing through it.
I = V/R = 120/15 = 8 A
Answer:
the amount of heat of energy released or absorbed by a substance.
Explanation:
Mathematically, latent heat of fusion is given by the formula;
Q = mL
Where;
Q is the quantity of heat energy measured in Joules.
m is the mass measured in kilograms.
L is the specific heat latent heat of fusion.
In the formulas for latent heat of fusion and latent heat of vaporization, Q represents the amount of heat of energy released or absorbed by a substance.
In the process of heat conduction, thermal energy is usually transferred from fast moving particles to slow moving particles during the collision of these particles. Also, thermal energy is typically transferred between objects that has different degrees of temperature and materials (particles) that are directly in contact with each other but differ in their ability to accept or give up electrons.
