Question
Chapter 5, Problem 5.4QAP
Interpretation Introduction
Interpretation:
The reason for the shielding to be vital in the glass electrodes design having value of an internal resistance
Concept introduction:
Glass electrode act as a chemical sensor, it uses a glass membrane as a surface for sensing. This is opposite to the one that uses a solid-state membrane or an organic membrane. In the glass, a material is present which is sensitive to the material which needs to be measured. Shielding is important when designing glass electrodes.

Resistors are electrical components that help to control the flow of the current in a circuit; they restrict the flow of electrons. ) Resistors consist of two pieces of conducting material separated by an insulating material called a dielectric. They are often used as timing devices, but they can transform electrical currents in other ways, too. ) Resistors can switch tiny electric currents on and off or amplify them.arrow_forward
