Which of the patient’s limbs serves as an electrical ground? In reality, only three limb leads are actually used to generate recordings; the right leg lead serves as an electrical ground.
Is sugar a conductor or insulator? Sugar does not conduct electricity because in sugar’s formula,C12H22O11 there are carbon,hydrogen and oxygen since we know that these are non metals and non metals are insulators of electricity so sugar does not conduct electricity.
Why is glucose not a good conductor of electricity? Glucose and alcohol are not ionic compounds, but they are covalent because electrons are shared instead of transferred between two atoms. … In the case of alcohol and glucose, no free ions are there, so the only presence of H is not sufficient. Hence, alcohol and glucose do not conduct electricity.
Is sugar an electrical insulator? A nonelectrolyte is a chemical that dissolves in water without producing ions. An aqueous solution of a nonelectrolyte usually doesn’t conduct an electric current. Examples of nonelectrolytes include sugar (C12H22O11), ethanol (CH3CH2OH), and acetone (CH3OCH3).
