What is Charge Value C vs. e?

Charge Value C refers to the amount of electric charge measured in coulombs, while e represents the elementary charge, approximately equal to 1.6 x 10^-19 coulombs.

What is Coulomb's Law?

Coulomb's Law states that the force between two charged objects is directly proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance between them.

What does E-Field Strength measure?

E-Field Strength, or Electric Field Strength, measures the force exerted per unit charge in an electric field, typically measured in volts per meter (V/m).

What is the relationship between Voltage and Energy?

Voltage, or electric potential difference, is the amount of energy per unit charge; it indicates how much work can be done by an electric field on a charge.

What charge does an electroscope acquire when a rubber rod is used for conduction?

An electroscope acquires a negative charge when a rubber rod, which typically has a negative charge due to electron transfer, is used for conduction.

What charge does an electroscope acquire when a glass rod is used for conduction?

An electroscope acquires a positive charge when a glass rod, which typically has a positive charge due to losing electrons, is used for conduction.

What is the principle of charging by conduction with a rubber rod?

The principle of charging by conduction with a rubber rod involves transferring electrons from the rubber to the electroscope, resulting in a net negative charge on the electroscope.

What is the principle of charging by conduction with a glass rod?

The principle of charging by conduction with a glass rod involves transferring electrons from the electroscope to the glass rod, resulting in a net positive charge on the electroscope.

Why does the charge on an electroscope change during conduction?

The charge on an electroscope changes during conduction because electrons are transferred between the electroscope and the charged rod, either adding or removing electrons from the electroscope.

What is charging by induction with a rubber rod?

Charging by induction with a rubber rod involves bringing a negatively charged rubber rod close to the electroscope, causing electrons in the electroscope to be repelled, leading to a net positive charge on the side of the electroscope closest to the rod.

What charge does an electroscope acquire when charged by induction with a rubber rod?

When charged by induction with a rubber rod, the electroscope acquires a net positive charge due to the repulsion of electrons.

What is charging by induction with a glass rod?

Charging by induction with a glass rod involves bringing a positively charged glass rod near the electroscope, causing electrons in the electroscope to be attracted to the side closest to the rod, resulting in a net negative charge on that side.

What charge does an electroscope acquire when charged by induction with a glass rod?

When charged by induction with a glass rod, the electroscope acquires a net negative charge due to the attraction of electrons.

Why does the charge on an electroscope change during induction?

The charge on an electroscope changes during induction because the presence of a charged rod causes redistribution of electrons within
