What is the equivalent resistance between points A and B?

Physics

insens350 [35]3 years ago
7 0
All the 3 resistors below point A and B are in series. These 3 resistors can be replaced by an equivalent resistor of resistance R = 1+1+1 = 3 kΩ 

Now, this R and 1 kΩ resistor are in parallel because they have common end points. And they can be replaced by an equivalent resistor of resistance 
R' = 3x1/3+1 = 3/4

Let the resistance of an electrical component remain constant while the potential difference across the two ends of the componen
slamgirl [31]

Answer:

The current through it will also decrease to half of its former value because according to Ohm's law the current flowing through a resistor is directly proportional to the potential difference applied across its ends provided that the temperature and some other necessary conditions remain constant.

This is mathematically represented as follows;

V=IR.........(1)

The current is thus given as

I=\frac{V}{R}..............(2)

if R is constant and V is reduced to half, then we have the following;

I=\frac{V/2}{R}

Simplifying further we obtain

I=\frac{V}{2R}...........(3)

Equation (3) shows that the current I is also reduced to half.

laila [671]

Answer:

f = 2 Hz

Explanation:

The frequency of a wave is defined as the no. of waves passing per unit of time. Therefore, the frequency of a wave can be calculated by the following formula:

f = \frac{n}{t}

where,

f = frequency of the wave = ?

t = time passed = 1 s

n = no. of waves passing in time t = 2

Therefore,

f = \frac{2}{1\ s}

<u>f = 2 Hz</u>

Why are heat transfers associated with phase changes known as latent or "hidden" heats?
pshichka [43]
The best and most correct answer among the choices provided by your question is the first choice or letter A.

Heat transfers associated with phase changes known as latent or "hidden" heats because h<span>eat absorbed or released in a phase change is measured in kJ while temperature is measured in °C.</span>

In which one of the following situations does a car have a WESTWARD acceleration? The car travels westward and slows down. The c
DENIUS [597]

Explanation:

Let east direction is negative and west direction is positive. The acceleration of an object is given by :

a=\dfrac{v-u}{t}

Where

v is the final speed

u is the initial speed

t is the time taken

As the car decelerates, the final speed of the car is less as compared to the initial speed. As a result, its acceleration is negative. It means the car travels eastward and slows down. Hence, this is the required solution.
