Question

The magnitude of the electric charge (e) is given by ____________

(a) -1.6*10^-19 C

(b) 1.6*10-^19 C

(c) 9.11*10-^31 C

(d) 1.637*10^-37 C

I have been asked this question by my school teacher while I was bunking the class.

My question is based upon The Temperature Dependence of P-N Characteristics in chapter Semiconductor-Diode Characteristics of Electronic Devices & Circuits

Answer 1

Correct choice is (a) -1.6*10^-19 C

For explanation I would say: The charge of the electron is the magnitude of electric force that an electron exerts on other particles which is equal to -1.6*10^-19 C, the negative sign indicates the direction of force.
