11.1 Electric Current and Circuit: Electric current is the amount of electricity flowing through a certain area in a certain amount of time. Basically, it's the speed at which electric charges move. In circuits with wires made of metal, the current is made up of electrons.

11.2 Electric Potential and Potential Difference: Electric potential (also known as voltage (V)) is the potential energy (potential energy per unit charge) at a point in the electric field. It is the work done to transfer a positive test charge (usually an infinite number of charges) from one point in the field to another. Potential difference (ΔV) is the difference in the electric potential between two points in the electric circuit.

11.3 Circuit Diagram: Circuit diagrams, also known as electrical diagrams, are graphical representations of an electrical circuit using standardized symbols.

11.4 Ohm’s law: Ohm's law is a fundamental concept in the field of electrical engineering, which describes the relationship between the voltage, current, and resistance of an electrical circuit.

11.5 Factors on which the resistance of a conductor depends: A conductor’s resistance is determined by several elements that affect how easily electrons can pass through it. Together, these elements determine how much resistance a conductor provides to electrons.

11.6 Resistance of a system of resistors: The overall resistance of a series of resistors that are connected in different series or parallel configurations can be determined by particular formulas that are based on the configuration of the individual resistors.

Subtopics covered in the section 11.6 Resistance of a system of resistors:

11.6.1 Resistors in Series

11.6.2 Resistors in Parallel

11.7 Heating Effect of Electric Current: If the electric circuit is only made up of resistors that are connected to a battery, the heat from the source will be completely dissipated. This is called the heating effect of electric current and it's used in devices like electric heater and electric iron.

Subtopics covered in the section 11.7 Heating Effect of Electric Current:

11.7.1 Practical Applocation of Heating Effect of Electric Current

11.8 Electric Power: Electric power is how fast electricity is created, transferred, or used in an electrical system or device. Basically, it's the speed at which electricity is converted from one form of energy to another.

## Key Points of Class 10 Science Chapter 11

• An electrical circuit is a series of conductive wires that run in a closed circuit to carry an electrical current. An electrical circuit is made up of elements such as resistors and capacitors, as well as switches and voltage sources.

• Electric current describes the flow of electrical charges ṣacross a conductor. Electrical current is measured in amperes.

• Electric potential is how much energy there is to move a charge through a circuit. It's measured in volts. Batteries and generators are the main sources of electric potential.

• The resistance of a material to an electric current is determined by its ohm (Ω) value. Materials with a high resistance are called insulators, and materials with a low resistance are called conductors.

• In series circuits, all the parts are connected in one direction. The current flows through all the parts and the voltage is the same. In parallel circuits, the parts are connected across each other's points. The current flows across all the parts, but the voltage is different.
