How are the current and resistance related when the voltage of a circuit is constant

2 answers:

3 0

The law of Ohm defines the relationship in an electrical circuit between voltage, current and resistance: I = v / r. The current is directly proportional to the voltage and the resistance is inversely proportional.

Answer:

I ∝ $\frac{1}{R}$ , current is inversely proportional resistance.

Explanation:

According to ohm's law :Voltage is directly proportional to the current

V ∝ I

V = IR.

We can write it as $\frac{V}{R}$ = I

We can say current is inversely proportional to resistance .

I ∝ $\frac{1}{R}$

Where , V = constant

Therefore, If voltage is constant current is inversely proportional resistance.

What happens to the force between two charges if one of the charges are doubled?

Julli [10]

Answer:

The new force between the charges becomes double of the initial force.

Explanation:

The force acting between charge particles is given by :

$F=k\dfrac{q_1q_2}{r^2}$

k is electrostatic constant

r is distance between charges

If one of the charges are doubled, then, q₁ = 2q₁

The new force becomes,

$F'=\dfrac{2kq_1q_2}{r^2}\\\\F'=2F$

So, the new force between the charges becomes double of the initial force.

A plane passes over Point A with a velocity of 8000 m/s north. Forty seconds later it passes over Point B at a velocity of 10,00

Airida [17]

Answer:

The planes’ acceleration from A to B is 500m/s^2

Explanation:

Given that the initial velocity u is 8000m/s

and also given the final velocity v=10,000 m/s

the time taken to move from A to B = 40 second

The acceleration is defined as the rate of change of velocity with time

we know that the expression for acceleration is given as

a=(v-u)/t

substituting our given data into the expression for a we have

a=(10000-8000)/40

a=2000/40

a=500m/s^2

The planes’ acceleration from A to B is 500m/s^2

Briefly describe the formation of the planets from the solar nebula

saul85 [17]

<span>The formation of the Solar System began 4.6 billion years ago with the gravitational collapse of a small part of a giant molecular cloud. Most of the collapsing mass collected in the center, forming the Sun, while the rest flattened into a proto-planetary disk out of which the planets, moons, asteroids, and other small Solar System bodies formed.

Hope it helped
