Electricity
विद्युत
Class 10 Science Chapter Electricity introduces electric current, potential difference, and the relationship between them through Ohm’s law. Students learn how resistance affects current in conductors, how electrical energy produces heat, and how these ideas are applied in simple circuits. The chapter also explains the basic arrangement and safe use of domestic electric circuits, helping students connect scientific concepts with everyday electrical appliances.
1Electric current
विद्युत धारा
In this Class 10 Science topic from the chapter Electricity, students learn how electric charge flows through a conductor and what is meant by electric current. They explore its conventional direction, SI unit (ampere), and measurement using an ammeter. The topic also connects current with potential difference and resistance, helping students understand simple electric circuits, apply the relation between these quantities, and interpret everyday uses of electricity safely and scientifically.
1 questionsPotential difference
विभवांतर
In this Class 10 Science topic from the Electricity chapter, students learn that potential difference is the work done to move a unit charge between two points in an electric circuit. They explore the relation V = W/Q, understand the volt as its SI unit, and learn how a voltmeter measures it when connected in parallel. The topic also explains why potential difference drives current and how it connects with resistance and Ohm’s law in simple circuits.
0 questionsOhm’s law
ओम का नियम
In Class 10 Science, the topic Ohm’s law introduces the relationship between potential difference, current, and resistance in an electric circuit. Students learn the formula V = IR, understand how voltage and resistance affect current, interpret the straight-line voltage–current graph for an ohmic conductor, and use the law to calculate unknown electrical quantities. The topic also builds a foundation for analysing simple circuits in the chapter Electricity.
1 questionsResistance
प्रतिरोध
In Class 10 Science, the topic Resistance introduces how a conductor opposes the flow of electric current in the chapter Electricity. Students learn Ohm’s law and the relationship between voltage, current, and resistance, expressed as V = IR. They explore how resistance depends on a material’s length, cross-sectional area, and temperature, and apply these ideas to understand resistors, circuit calculations, and the effects of connecting resistors in series and parallel.
1 questionsHeating effect of current
विद्युत धारा का ऊष्मीय प्रभाव
In Class 10 Science, this topic explains how electrical energy changes into heat when current passes through a conductor. Students learn Joule’s law of heating, the factors that affect heat produced—current, resistance and time—and how to apply the relationship in numerical problems. The lesson connects the heating effect of current with practical devices such as electric irons, heaters, incandescent bulbs and fuses, while building understanding of safety and energy use within the Electricity chapter.
0 questionsDomestic Electric Circuits
घरेलू विद्युत परिपथ
In this Class 10 Science topic from the chapter Electricity, students learn how electrical energy is distributed and used safely in homes. The topic explains live, neutral and earth wires, the role of switches, fuses and circuit breakers, and why household appliances are connected in parallel. Students also connect these ideas with electric current, potential difference, resistance, power and energy, while understanding common causes of short circuits, overloading and electric shocks.
