The atoms combine with each other by the transfer or mutual sharing of electrons and in doing so, each combining atom attains the inert gas configuration. The outermost shell of atoms of the inert gases have 8 electrons
and are most stable. 41. 3544 Jasa fuqu vel 38 (a), (b), (c) GROTI 42. (a) Satish K. Gupta, op. cit, p. 30 —
"Concept of electric field Consider that an electric charge q is present at some point in space. If we bring any other charge say q near the charge q, it will experience a force of attraction or repulsion due to the charge q. The force experienced by the charge q is said to be due to the electric field set up by the charge q. The electric field of a charge is the space property by virtue of which the charge modifies the space around itself. As a result, if any other charge is brought in the space around the charge, it experiences electrostatic force. Thus, electric field due to a charge is the space around the charge,
in which any other charge is acted upon by an electrostatic force." (b) Ibid., p.161-''The electric field is the space around an electric
charge in which its effect can be experienced." 43. Ibid., p. 222 —
"Electric Current "'It is defined as the rate of flow of electric charge through any section of a wire. It is denoted by I. Then I = total charge flowing / time taken If charge q flows in a timet through any section of a wire, then I=q/t If n carriers of electricity, each having charge e, cross any section of the conductor in time t then I = ne/t If charge dq flows through a wire in small time dt, then I = dq/dt The direction in which the positive charge will flow gives the direction of conventional current. Since the flow of current is attributed to flow
