Question

Electric current is defined as a flow of
a. electric charge in units of volts per s.
b. protons in units of protons per s.
c. electric charge in units of coulomb per s.
d. electrons in units of electrons per s.

Answer 1

$\mathcal\huge{\red{Answer:}}$

c. electric charge in units of coulomb per second.

$\mathcal\huge{\green{More\:to\:know}}$

• Electric Current is the flow of electrons through a wire or solution.
• In a solid the electrons are passed from one positively charged metallic atom to next but in solution the electron is carried by the ions present in the solution.
• A solution capable of carrying charge is called an electrolyte.

The conventional direction of electric current is taken as opposite to the direction of flow of electrons. If a charge Q flows through the cross-section of a conductor in time t, the current I then,

$\bold\sf{ I={\dfrac{Q}{t}}}$.

The S.I unit of charge is Coulomb and measurement of electric current happens in units of coulomb per second which is ‘Ampere’. The current flows from the negative terminal to the positive terminal of the cell.

Answer 2

c. electric charge in units of coulomb per s.

Additional information :

• SI unit: coulomb

• Denoted by : Q

• Electric charge is a basic property of matter's Particles .

★━━━━━━━━━━━━★★━━━━━━━━━━━━★

• Electric charge is conserved and quantized.

➡️ I.e charge can neither be created nor be destroyed but can be transformed from one form to another.

➡️ The charges are present in the form of either one with positive nature and another with negative while positive and positive repel each other so happens in the case of two negative charge.

On the other hand two positive and negative charge attract each other and vice versa..

From above statement it can be concluded that similar charges repel each other while the positive always attracts..
