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.
<h3>What is Ohm's law?</h3>
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.

La energía limpia es energía libre de carbono que genera poca o ninguna emisión de gases de efecto invernadero. ... La energía renovable es la energía que proviene de recursos que se reponen naturalmente, como la luz solar, el viento, el agua y el calor geotérmico.
Hi there!
First, let's find the period of the pendulum. This can be found by solving for the amount of time it takes for the pendulum to make ONE complete swing.
Now, let's use the equation for the period of a simple pendulum:
T = Period (1.318 s)
L = length of string (0.55 m)
g = acceleration due to gravity on planet (? m/s²)
Let's solve for 'g' doing some quick rearranging of the equation:
Solving for 'g' by plugging in values:
Answer:
C. Both A and B
Explanation:
Fuses are rated by the amperage they can carry before heat melts the element. The fuse is ideal for protection against short circuits. Short circuits produce enough amperage to vaporize a fuse element and break connection in one cycle of a 60-cycle system.
Specifically, the voltage rating determines the ability of the fuse to suppress the internal arcing that occurs after a fuse link melts and an arc is produced.
