Answer 1

Answer:

vc is the answer

okkkkkkkk

Answer 2

Answer:

(a) Quantity measured by the unit VC = Joule

(b) Quantity measured by the unit Cs⁻¹ = Ampere

Explanation:

(a)

As we know that the unit of energy is defined as Joule and Power is defined as the rate of energy transformed from one form to another. Hence,

Power (watt) = Joule/seconds

So,

Joule = watt × seconds

Also,

Power = voltage × current

Hence,

Joule = voltage × ampere × seconds

As we know that Current is defined as the rate of change of charge.

1 Ampere = Coulomb/seconds

so,

Coulomb = ampere × seconds

Hence,

Joule = voltage × Coulomb

(b)

As we know that the flow of 1-coulomb charge per second is defined as Ampere.

Also,

The SI unit of electric current is known as Ampere.

Hence,

1 Cs⁻¹ = 1 Ampere
