Electric current is the flow of electric charge. In simpler terms, it's the movement of electrons through a conductor like a wire

AC (Alternating Current) changes its direction periodically, while DC (Direct Current) flows in one direction consistently.

An electric circuit is a closed path that allows electric current to flow. It typically consists of a power source, conductors, and a load.

Electric potential is the electric potential energy per unit charge at a point in an electric field. It's measured in volts.

Potential difference, or voltage, is the difference in electric potential between two points in a circuit. It's the driving force that makes electric charges move.

A switch is represented by a break in the circuit line with a gap, which can be closed or opened to control the flow of current.

A circle represents a light bulb or any other electrical load in a circuit diagram.

Ohm's Law states that the current passing through a conductor between two points is directly proportional to the voltage across the two points, provided the temperature remains constant.

Using Ohm's Law (R = V/I), the resistance is 4 ohms.

The resistance of a conductor depends on its length, cross-sectional area, temperature, and the material it's made of.

Generally, an increase in temperature increases the resistance of a conductor.

In a series circuit, resistances add up. The total resistance (R_total) is the sum of individual resistances.

In a parallel circuit, the reciprocal of the total resistance is equal to the sum of the reciprocals of individual resistances.

When electric current passes through a conductor, it produces heat due to the collisions between electrons and atoms in the conductor.

The heating effect is used in appliances like electric heaters and stoves to generate heat for various purposes.

Electric power is the rate at which electric energy is transferred or converted, measured in watts (W). .

Electric power (P) is the product of voltage (V) and current (I), expressed by the formula P = VI. .

Fuses protect electrical circuits by melting and breaking the circuit when the current exceeds a safe limit, preventing damage to devices and fires. .

Electrical grounding provides a path for electric current to flow safely into the ground, preventing electric shocks and ensuring safety. .

Generally, a thinner wire has higher resistance than a thicker wire. This is because a thicker wire allows for more electrons to flow, reducing resistance. .
