An electric heater carries a current of 13.5 A when operating at a voltage of 120V . What is the resistance of the heater?

1 answer:

4 0

An electric heater that carries a current of 13.5 A when operating at a voltage of 120V , will have the resistance of the heater as 8.89 ohm.

Ohm's law can be described as the law in physics that focus on how voltage or potential difference between two points is directly proportional to the current or electricity that is moving in the direction of the resistance.

An this is also directly proportional to the resistance of the circuit, hence it can be calculated using the Ohm's law is V=IR.

from V=IR

R=V/I

= 120/13.55

=8.89 ohm.

Therefore, electric heater that carries a current of 13.5 A when operating at a voltage of 120V , will have the resistance of the heater as 8.89 ohm.

Answer: The answer is in the figure attached.

Explanation:

The Work $W$ done by a Force $F$ refers to the release of potential energy from a body that is moved by the application of that force to overcome a resistance along a path.

It should be noted that it is a scalar magnitude, and its unit in the <u>International System of Units</u> is the Joule (J). Therefore, 1 Joule is the work done by a force of 1 Newton when moving an object, in the direction of the force, along 1 meter:

$1J=(1N)(1m)=Nm$

However, in the British Engineering and Gravitational Systems its unit is Foot-pound (ft-lb). Where $1ft-lb=1.355818J$

Now, when the applied force $F)$ is constant and the direction of the force and the direction of the movement (traveled distance) $d$ are parallel, the equation to calculate it is:
