The important point of Chapter 12 Science Class 10


1.    A stream of electrons moving through a conductor constitutes an electric current. Conventionally the direction of current is taken opposite to the direction of the flow of electrons.



2.    The SI unit of electric current is Ampere.



3.    To set the electrons in motion in an electric circuit. We use a cell or a battery. A cell generates a potential difference across its terminals. It is measured in Volts.



4.    Resistance is a property that resists the flow of electrons in a conductor.it controls the magnitude of the current. The SI unit of resistance is the ohm.



5.    Ohm’s law: The potential difference across the ends of a resistor is directly proportional to the current through it, provided its temperature remains the same.



6.    The resistance of a conductor depends directly on its length, inversely on its area of cross-section, and also on the material of the conductor.


7.    The equivalent resistance of several resistors in a series is equal to the sum of their individual resistances.


8.    The electrical energy dissipated in a resistor is given by W= V × I × t


9.    The unit of power is Watt, one watt of power is consumed when 1A of current flows at a potential difference of IV.


10.       The commercial unit of electrical energy is a kilowatt-hour (kWh).


11.       Electrical current is measured by an instrument called Ammeter. Ammeter is always connected in series in an electrical circuit.


12.       Potential difference is measured by an instrument called a voltmeter. A voltmeter is always connected in parallel in an electric circuit.


13.       Electric fuse: is a safety device which works on the principle of heating effect of electric current and it protects the electrical appliances from being damaged.

Frequently  Asked Questions 


 1. What is Ohm's law answer?

The potential difference across the ends of a resistor is directly proportional to the current through it, provided its temperature, length, and area of cross-section and material remain the same.

 

2. What is meant by the resistance of a conductor?

Resistance is the basic property of any material. Resistance is the property that resists the flow of electrons in a conductor. It controls the magnitude of the current.

 

 3. What is the cause of resistance of a conductor Class 10?

In class 10 12th chapter is electricity. A conductor has free electrons or ions in it that are the main cause of resistance, these free ions resist the flow of current in a conductor.

 

 4. What is ohm's law explain class 10th?

The potential difference across the ends of a resistor is directly proportional to the current through it, provided its temperature, length, and area of cross-section and material remain the same.

 

 5. What is the electricity definition for class 10?

A stream of electrons moving through a conductor constitutes an electric current. The rate of flow of charge is defined as electric current. SI unit of electric current is ampere.
