Get NCERT Exercise Solution Class 10 Science Chapter 11 Electricity. Electricity :  Electricity is a controllable and convenient form of energy and defined as the flow of electric charge.   Electric Charge  :  Electric charge can be defined as a fundamental property of subatomic particles that gives rise to the phenomenon of experiencing force in the presence of electric and magnetic fields. Some  properties of electric charge 1.  Electric charges are of two types - Positive charges or protons have a charge of $+1.6 × 10^{-19}$ Coulomb. Negative charges or Electrons have a charge of $-1.6 × 10^{-19}$ Coulomb. 2. Charge is a scalar quantity. 3. Charge is transferable, Charge( Electron) transfer from one body to another. 4. Like charges repel each other and unlike. charges attract each other. 4. Charge is always ...

NCERT Exercise Solution Class 10 Science Chapter 11 Electricity  Example 11.1 A current of 0.5 A is drawn by a filament of an electric bulb for 10 minutes. Find the amount of electric charge that flows through the circuit. Solution: Given  I = 0.5 A ,   t = 10 min = 600 s. We have Q = It = 0.5 A × 600 s = 300 C Page Number 172 – Question with solution 1 to 3 : 1. What does an electric circuit mean? Solution : It is a continuous and closed path through which electric current flows. It contains different components like • Cell or Battery Plug Key • Wires • Electric Components (like Ammeter,Voltmeter) • Bulb etc  2. Define the unit of current. Solution :  The unit of electric current is ampere (A). I  = $\frac{Q}{t}$ When Q = 1 C and t = 1 sec then I = $\frac{1C}{1S}$ I = 1A 1 A is defined as the flow of 1 C of charge through a wire in 1 s. 3. Calculate the number of electrons constituting one coulomb of charge. Solution :  We know  Q...
