Biogas or gobar gas is produced by anaerobic breakdown or digestion of biomass.
Biogas or gobar gas is a methane-rich fuel gas produced by anaerobic breakdown or digestion of biomass with the help of methanogenic bacteria. It is made up of methane (50 - 70%), carbon dioxide (30 - 40%) with traces of nitrogen, hydrogen sulphide, and hydrogen.
Therefore, the correct option is C) methane.
AB is a part of an electrical circuit (see figure). The potential difference \(V_A - V_B\), at the instant when current \(i = 2\) A and is increasing at a rate of 1 amp/second is:
