Which of the following units is used to express electrical charge? Question 2 options: Newton Coulomb Joule

Respuesta :

The coulomb whose symbol is (C),  is used to express charge. It is the SI unit of  electric charge.

1 C is equivalent to charge carried by 6.24×10¹⁸ electrons. Although electrons are negatively charged, the Coulomb expresses both positive and negative charges.

Answer: Coulomb

Explanation:

[tex]Q=I\times t[/tex]

where Q= quantity of electricity

I = current in amperes

t= time in seconds

Thus charge is in coulomb. 1 coloumb of charge appears whe 1 ampere current is passed for 1 second.

Newton is the unit of force.

[tex]1kgms^{-2}=1Newton(N)[/tex]

Joule is the unit of energy.

[tex]1kgm^2s^{-2}=1 Joule[/tex]
