I attach a voltage source to a 45 mF capacitor until it is fully charged. I then take the voltage source away and discharge the

capacitor through a 120 Ω resistor in a basic RC circuit. If the initial current through the circuit during discharge is 0.5 A, what voltage did I apply to the capacitor to charge it?

Answer:

60 V

Explanation:

Let the potential on capacitor be V . This will be equal to voltage of the source .

During discharge this voltage of capacitor will create current .

V / 120 = .5

V = 60 V

So this would have been the voltage of the source . So voltage of source

= 60 V

Answer:

V=60\;volt\\

Explanation:

Given,

C=45\;mF\\R=120\;\Omega\\i=0.5\;A

By the ohm's law,

V=iR\\V=0.5times120\\V=60\;volt\\

Natalija [7]

As the resistance of a circuit increases, the current will decreases.

<h3>What is ohm’s law?</h3>

Ohm's law claims that the voltage across a conductor is directly proportional to the current flowing through it.

When all physical parameters and temperature are constant,

Ohm's law claims that the voltage across a conductor is directly proportional to the current flowing through it.

This current-voltage connection may be expressed mathematically by Ohm's law as;

V=IR

If the voltage is constant, the resistance of the circuit will be inversely proportional to the current.

Hence,as the resistance of a circuit increases, the current will decreases.

When light is directed on a metal surface, the kinetic energies of the photoelectrons a) are random b) vary with the frequency o
jekas [21]

Answer:

b) vary with the frequency of the light

Explanation:

The phone electric effect can be expressed as

K.E=(hv -W•)

Where K.E is the Kinectic energy

W• = work function of the metal

ν =frequency of the radiation

h = Planck's constat

Then, we can see that K.E is proportional linearly to "v" in the equation above.

Therefore, When light is directed on a metal surface, the kinetic energies of the photoelectrons vary with the frequency of the light

Describe the similarities and differences between an exercise and diet program that can improve bone health for a 16-year old bo
maxonik [38]

Answer: The similarity in between the the diet plan of the 16 year old boy and 52 years old women is that they both should focus on their bone health.

Both of them should have a proper intake of calcium in their body so as to have healthy bones.

The differences is that the digestive system of both is different, the 16 old boy can have rich diet and can digest it.

But the 52 year old women cannot have such diet which contains fat, cholesterol and hard to digest diet.

The similarity in exercises is that they should have proper movement in their body so as to maintain the flexibility.

Based on the body's capacity to do exercise there will be different exercises assigned to both a 16 year old boy and 52 year old women.
