Ohm's law relates the current, voltage, and resistance in a circuit. Use Ohm's law to determine what will happen to the remainin

g variable if one is held constant and another is changed. Assume that, originally, the resistance is R 0 , the current is I 0 , and the voltage is V 0 .

Answer:

Ohm's Law states that current through any conductor is directly proportional to the potential difference across the ends of the conductor.

Explanation:

Ohm's Law states that current through any conductor is directly proportional to the potential difference across the ends of the conductor.

<u>Mathematically:</u>

I\propto V

I_0=\frac{V_0}{R_0}

where

R = resistance of the conductor

i.e.

  • When resistance is held constant the current is directly proportional to the voltage.

Other form of the equation is:

V_0=R_0.I_0

  • For a constant current the voltage is directly proportional to the resistance of the conductor.

V_0\propto R_0

  • For constant voltage the current is inversely proportional to the resistance of the conductor.

I_0\propto \frac{1}{R_0}

Answer:

Explanation:

According to the Ohm's law, when the temperature of a conductor remains constant, the current flowing through the conductor is directly proportional to the potential difference applied across the conductor.

V = I R

where, I is the current and R be the resistance of the conductor.

When the resistance remains constant, if we increase the potential difference across the conductor, the current also increases.

A positive kaon (K+) has a rest mass of 494 MeV/c² , whereas a proton has a rest mass of 938 MeV/c². If a kaon has a total energ
vitfil [10]

Answer:

<em>0.85c </em>

Explanation:

Rest mass of Kaon M_{0K} = 494 MeV/c²

Rest mass of proton M_{0P}  = 938 MeV/c²

The rest energy is gotten by multiplying the rest mass by the square of the speed of light c²

for the kaon, rest energy E_{0K} = 494c² MeV

for the proton, rest energy E_{0P} = 938c² MeV

Recall that the rest energy, and the total energy are related by..

E = γE_{0}

which can be written in this case as

E_{K} = γE_{0K} ...... equ 1

where E = total energy of the kaon, and

E_{0} = rest energy of the kaon

γ = relativistic factor = \frac{1}{\sqrt{1 - \beta ^{2} } }

where \beta = \frac{v}{c}

But, it is stated that the total energy of the kaon is equal to the rest mass of the proton or its equivalent rest energy, therefore...

E_{K} = E_{0P} ......equ 2

where E_{K} is the total energy of the kaon, and

E_{0P} is the rest energy of the proton.

From E_{K} = E_{0P} = 938c²    

equ 1 becomes

938c² = γ494c²

γ = 938c²/494c² = 1.89

γ = \frac{1}{\sqrt{1 - \beta ^{2} } } = 1.89

1.89\sqrt{1 - \beta ^{2} } = 1

squaring both sides, we get

3.57( 1 - \beta^{2}) = 1

3.57 - 3.57\beta^{2} = 1

2.57 = 3.57\beta^{2}

\beta^{2} = 2.57/3.57 = 0.72

\beta = \sqrt{0.72} = 0.85

but, \beta = \frac{v}{c}

v/c = 0.85

v = <em>0.85c </em>
