Three resistors, of 100, 200, and 300 ohms are connected in parallel. What is their equivalent resistance?

(Unit = ohms)

Answers

Answer 1

Answer:

Equivalent resistanfe in parallel (R):

1/R = 1/100 + 1/200 + 1/300

1/R = (6 + 3 + 2)/600

1/R = 11/600

R = 600/11 = 54.55 ohms

Answer 2

Equivalent resistance is 54.55Ω.

It is given that three resistors are,

[tex]R_{1}[/tex] = 100Ω, [tex]R_{2}[/tex] = 200Ω, and [tex]R_{3}[/tex] =300Ω

It is required to find the equivalent resistance when resistors connected in parallel.

What is the equivalent resistance?

As we know, when the resistors are connected in parallel,

[tex]\frac{1}{R} =\frac{1}{R_{1} } +\frac{1}{R_{2} }+\frac{1}{R_{3} }[/tex]

Putting the values, we have

[tex]\frac{1}{R} =\frac{1}{100} } +\frac{1}{200 }+\frac{1}{300 }[/tex]

[tex]\frac{1}{R} =\frac{(6+3+2)}{600}[/tex]

[tex]\frac{1}{R} =\frac{11}{600}[/tex]

[tex]R=\frac{600}{11}[/tex]

R=54.55Ω

 

Thus, equivalent resistance or total resistance when resistance are connected in parallel is 54.55Ω.

As an ice cube melts, its molecules

A. absorb heat energy and move farther apart

B. absorb heat energy and move closer together

C. release heat energy and move farther apart

D. release heat energy and move closer together
​

Answers

Answer:

A. absorb heat energy and move farther apart

Explanation:

The answer is A since when a ice cube takes in heat, it changes form and melts down to a liquid : water.

The molecules in water are farther apart since they are moving around alot but can be contained in a container.

Describe how an earth wire and a fuse can protect an iPad with a metal casing

- 5 clear simple points

Answers

Answer: Find the answer in the explanation.

Explanation:

The earth wire act as a protective conductor in which hazardous current flows to the earth. Whenever there is a faulty flow of current, the earth wire will protect an iPad with a metal casing from eddy current by allowing the faulty current to flow directly to the earth.

With the use of fuse, an iPad with a metal casing will be protected from extreme heat due to overheating or electrical overloading as a result of short circuit.
