CBSE NCERT Solutions Class 10 Science Chapter 12 Electricity.� NCERT Solutions have been prepared by academic experts with decades of teaching experience. They have prepared the solutions in the most simple manner so that each and every student can understand the concepts well. All the solutions have been explained in detail and the answers have been compiled in a step-wise manner. 3. Static and current electricities: Static electricity deals with the electric charges at rest while the current electricity deals with the electric charges in motion. 4. Conductor: A substance which allows passage of electric charges through it easily is called a ?conductor�. A conductor offers very low resistance to the flow of current. For example copper,silver, aluminium etc. 5. Insulator: A substance that has infinitely high resistance does not allow electric current to flow through it. It is called an ?insulator�. For example rubber, glass, plastic, ebonite etc.

Please also refer to the NCERT solutions for Class 10 Science to understand the answers of the exercise questions given at the end of this chapter. We are familiar with air current and water current. We know that flowing water constitute water current in rivers. Similarly, if the electric charge flows through a conductor for example, through a metallic wire , we say that there is an electric current in the conductor. In a torch, we know that the cells or a battery, when placed in proper order provide flow of charges or an electric current through the torch bulb to glow.

We have also seen that the torch gives light only when its switch is on. What does a switch do? A switch makes a conducting link between the cell and the bulb. A continuous and closed path of an electric current is called an electric circuit.

Now, if the circuit Electricity Class 10th Ncert Pdf Template is broken anywhere or the switch Electricity Class 10th Ncert Pdf Iphone of the torch is turned off , the current stops flowing and the bulb does not glow. How do we express electric current? Electric current is expressed by the amount of charge flowing through a particular area in unit time. In other words, it is the rate of flow of electric charges. In circuits using metallic wires, electrons constitute the flow of charges.

However, electrons were not known at the time when the phenomenon of electricity was first observed. So, electric current was considered to be the flow of positive charges and the direction of flow of positive charges was taken to be the direction of electric current.

Conventionally, in an electric circuit the direction of electric current is taken as opposite to the direction of the flow of electrons, which are negative charges. We know that an electron possesses a negative charge of 1. The electric current is Electricity Class 10th Ncert Pdf Github expressed by a unit called ampere A , named after the French scientist, Andre-Marie Ampere � An instrument called ammeter measures electric current in a circuit.

It is always connected in series in a circuit through which the current is to be measured. Figure Note that the electric current flows in the circuit from the positive terminal of the cell to the negative terminal of the cell through Figure What does an electric circuit mean?

Define the unit of current. Calculate the number of electrons constituting one coulomb of charge. Name a device that helps to maintain a potential difference across a conductor. What is meant by saying that the potential difference between two points is 1 V?

How much energy is given to each coulomb of charge passing through a. A piece of wire of resistance R is cut into five equal parts. These parts are then connected in parallel. Which of the following terms does not represent electrical power in a circuit?

An electric bulb is rated V and W. When it is operated on V, the power consumed will be �. Two conducting wires of the same material and of equal lengths and equal diameters are first connected in series and then parallel in a circuit across the same potential difference. The ratio of heat produced in series and parallel combinations would be �. How is a voltmeter connected in the circuit to measure the potential difference between two points?

A copper wire has diameter 0. How much does the resistance change if the diameter is doubled? The values of current I flowing in a given resistor for the corresponding values of potential difference V across the resistor are given below �. I amperes 0. V volts 1. When a 12 V battery is connected across an unknown resistor, there is a current of 2.

Find the value of the resistance of the resistor. A battery of 9 V is connected in series with resistors of 0. Several electric bulbs designed to be used on a V electric supply line, are rated. How many lamps can be connected in parallel with each other across the two wires of V line if the maximum allowable current is 5 A? What are the currents in the three cases?
