What is the relationship between voltage, charge, and capacitance in an electrical circuit?
In an electrical circuit, voltage is directly proportional to charge and inversely proportional to capacitance. This means that as the voltage increases, the charge stored in the capacitor also increases, while capacitance decreases. Conversely, if capacitance increases, the voltage across the capacitor decreases for a given charge.
When the perspex rod is rubbed with nylon and the rod becomes positively charge what charge will be on the nylon?
a negative charge
What is the electric field due to a line of charge?
The electric field due to a line of charge is a vector field that points radially outward from the line of charge. Its magnitude decreases as the distance from the line of charge increases.
How does the strength of an electric field change as the distance from a charge decreases?
The strength of an electric field increases as the distance from a charge decreases. This relationship follows an inverse square law, meaning that the electric field strength is proportional to 1/r^2, where r is the distance from the charge.
How are dust particles negatively charged?
Dust particles become negatively charged when they gain extra electrons from their surroundings, causing them to have a surplus of negative charge.

What trend does electronegative following down the periodic table?
Electronegativity decreases along a period. This is because atomic radius increases increases, hence nuclear charge decreases.
How does an ion become Negatively charge?
it loses a proton or gains an electron
What trend does the electronegativity follow going down the periodic table?
Electronegativity decreases because the valence electrons are farther from the nucleus.
When the perspex rod is rubbed with nylon and the rod becomes positively charge what charge will be on the nylon?
a negative charge
When moving left to right across the periodic table the atomic number increases and the atomic radius?
The atomic radius decreases from left to right and increases from top to bottom
What is the electric field due to a line of charge?
The electric field due to a line of charge is a vector field that points radially outward from the line of charge. Its magnitude decreases as the distance from the line of charge increases.
How does size change in a period and in a group?
Atomic size decreases across a period as the effective nuclear charge increases. Atomic size increases down a group as the energy level (shells) increases.
How does the strength of an electric field change as the distance from a charge decreases?
The strength of an electric field increases as the distance from a charge decreases. This relationship follows an inverse square law, meaning that the electric field strength is proportional to 1/r^2, where r is the distance from the charge.
What happens to an atom's overall charge if it gains an electron?
since an electron is negatively charged, adding an electron to an atom will cause it to become negatively charged.
What kind of charge will nonmetal possess when it gains electron?
Since electrons are negatively charged, a nonmetal which gains an electron will also become negatively charged.
How are dust particles negatively charged?
Dust particles become negatively charged when they gain extra electrons from their surroundings, causing them to have a surplus of negative charge.
