The invention of the radio transmitter resulted from the convergence of two lines of research. One was efforts by inventors to devise a system to transmit telegraph signals without wires. Experiments by a number of inventors had shown that electrical disturbances could be transmitted short distances through the air. However m… WebPrinciple: The pH value of a solution is measured using a pH electrode. It consists essentially of a pair of electrodes, measurement and reference electrode, both submerged in the solution of unknown pH. These two electrodes essentially form two half cells. Web“commercial” interests such as those of Marconi with the idea that from here forward more powerful sparks and higher antennas were all that was needed to extend range.
