What is the easiest way to solve electricity Numericals Class 10?
Solved Electricity numerical for class 10
- (ii) Resistance of the filament of the bulb increases with increase in temperature.
- Answer: L = 1 km = 1000 m.
- (i) the resistance per unit length of the wire.
- Resistance per unit length: 2/5= 0.4 Ohm/m.
- (ii) Resistance of 2 m length of the wire = 0.4 x 2=0.8 ohm.
What are the formulas for electricity Class 10?
Tabular Form of Electricity Formula
Quantity | Formulas | Unit |
---|---|---|
Current I | I = Q / t Q = Charge t = time taken | Amperes (A) |
Voltage V | V = E / Q or V = W / Q E = Energy W = Work done | Volts (V) |
Resistance R | R = ρ*l / A ρ = Resistivity, l = length, A = Area or, R = V / I | Ohm (Ω) |
Power P | P = VI | Watts (W) |
What is heating effect of electric current class 10 Numericals?
Definition:When an electric current is passed through a conductor which acts as a resistance wire, the resisting nature of the conductor results in the rise in heat level of the conductor with time. This phenomenon is the heating effect of the electric current.
What are the Numericals?
indicating a number: numerical symbols. bearing or designated by a number. expressed by numbers instead of letters: numerical cryptography; numerical equations. of or relating to one’s skill at working with numbers, solving mathematical problems, etc.: tests for rating numerical aptitude.
What is the SI unit of electricity?
The ampere, symbol A, is the SI unit of electric current. It is defined by taking the fixed numerical value of the elementary charge e to be 1.602 176 634 ×10−19 when expressed in the unit C, which is equal to A s, where the second is defined in terms of ∆νCs.
What is Joules law of heating Class 10?
Joule’s law of heating states that, when a current ‘i ‘ passes through a conductor of resistance ‘r’ for time ‘t’ then the heat developed in the conductor is equal to the product of the square of the current, the resistance and time.
What is a numerical symbol?
In popular usage, numerical symbols are synonymous with numerals, such as the ubiquitous Hindu-Arabic numerals (1, 3, 5, etc.) or the Roman numerals (I, III, V, etc.). Numerical symbols also carry linguistic information in the form of number names (e.g., the numeral 5 is associated with the number word “five”).
Will current flow more easily?
The current will flow more easily through the thick wire than the thin wire. It is because the resistance of a conductor is inversely proportional to its area of cross-section. If the thicker the wire, the less is resistance and hence more easily the current flows.

How do you find the energy given to each Coulomb?
W is the work done in moving the charge from one point to another Q is the charge From the above equation, we can find the energy given to each coulomb as follows: W = V × Q
