Why are voltages always measured between two points??

Physics
1 answer:
sukhopar [10]3 years ago
7 0

Answer:

We describe electrical circuits similarly: current is the rate at which charge flows past a point, while the voltage is effectively like an electrical “pressure.” Voltage is always measured between two points and indicates the force “pushing” charges to flow from one point to another.

What is the resistance of a toaster that uses 2A when connected to a 120V power source?
denis23 [38]

Answer:

60 ohms

Explanation:

From Ohm's Law:

V = IR

Where V = 120volts

I = 2A

R = ?

Note that R,V and I represents resistance, voltage and current respectively.

Substituting the above values into the formula.

V = IR

120v = 2×R

120= 2R

Making R the subject

R =120/2

R = 60 ohms

Hence the resistance of the toaster will be 60 ohms.

A ball of mass 0.15 kg is dropped from rest from a height of 1.25 m. It rebounds from the floor to reach a height of 0.960 m. b)
Art [367]

Answer:

Explanation:

If v be the velocity just after the rebound

Kinetic energy will be converted into potential energy

1/2 m v² = mgh

v² = 2gh

v = √ 2gh

= √ 2 x 9.8 x .96

= 4.33 m / s

If our solar system's Sun was half the mass as it is now, what would happen to the orbit of the Earth
avanturin [10]
Essentially, an increase in mass means an increase in gravity, while a decrease in mass means a decrease in gravity. So if the Sun spontaneously lost half its mass (gasp, shudder, the horror!) then its gravitational pull on Earth would lessen as well, ultimately changing the very nature of our orbit around the Sun.
Thank You!
