What is a dielectric?
A dielectric is an insulating material that doesn’t conduct electric charge but supports an electric field. It is used in capacitors and insulators.
What is an electric circuit?
An electric circuit is a closed loop that allows the flow of electric current from a power source to various components and back to the source.
What are series and parallel connections in a circuit?
Series connections have components in a single path with equal current, while parallel connections have multiple paths with equal voltage across them.
How does an electric current flow in a conductor?
Electric current flows in a conductor when free electrons drift under the influence of an electric field, affected by factors like conductivity and temperature.
What is Ohm’s law?
Ohm’s Law states that the current flowing through a conductor is directly proportional to the voltage across it and inversely proportional to its resistance.
What are the units for charge, voltage, and capacitance?
The units for charge, voltage, and capacitance are Coulomb (C), Volt (V), and Farad (F), respectively, in the International System of Units (SI).
What is an electric current?
An electric current is the flow of electric charge through a conducting medium, such as a wire, and can be either direct (DC) or alternating (AC).
What is an insulator?
An insulator is a material that doesn’t conduct electric current easily, offering high electrical resistance, low thermal conductivity, and dielectric strength.
What is a conductor?
A conductor is a material that allows the flow of electric current due to the movement of free electrons, and is often used in power transmission.
What is capacitance?
Capacitance is the ability of a device, like a capacitor, to store electric charge and is measured as the ratio of charge stored to voltage applied.
