The resistance of an object depends on its shape and the material of which it is composed. The cylindrical resistor in Figure 1 is easy to analyze, and, by so doing, we can gain insight into the resistance of more complicated shapes What is the rheostat and variable resistance? Class 10th ques from electricity Thank you ♥️ 2 See answers GovindRavi GovindRavi Actually Rheostat is a Variable resistance, it means we can change the value resistance in the circuit.. According to Ohm's Law -> V = I x R or R = V/ Resistance is the property of a conductor, which determines the quantity of current that passes through it when a potential difference is applied across it. A resistor is a electrical componet with a predetermined electrical resistance, like 1 ohm, 10 ohms 100 ohms 10000 ohms etc Since resistance R is inversely proportional to the conductance s. For example, a car is moving at a speed of 10 kmph, keeping the distance as 1 km. The time will be 1/10 hr. It means if the resistance of the material of the conductor is 100 Ω, then the conductance will be 1/100 Ω. Here, you got another unit of conductor, and that is, 'mho.

Electrical Resistance - Definition, Unit, Formula, Measuremen

  1. ResistanceResistivityThe electrical resistance of an object is a measure of its opposition to the flow of electric current.Resistivity is the characteristic property of the material by which it resists the amount of current through it.It depends upon the length, area of cross-section and nature of
  2. The resistance, R of the eureka wire is the highest whereas the resistance, R of the copper wire is the lowest. The measure of a material's ability to oppose current flow is also known as the resistivity, p of the material
  3. Long resistance brazes mean heat buildup this pushes the capabilities of standard material and then one turns to: Hard carbon is a candidate for long hot welds RWMA Refractory Group B Class 10 - 14 are candidates Class 11 (Copper/Tungsten) is most frequently used
  4. Working on CBSE class 10 physics electricity questions and answers will help candidates to score good marks in-class tests as well as in the CBSE Class 10 board exam. Electricity class 10 NCERT solutions will not only help in board exam preparation but also helps in clearing the competitive exams like Engineering

The resistance of a conductor is very low whereas insulators have very high resistances. The resistance of a conducting wire is proportional to its length and inversely proportional to its cross-sectional area. Resistance is a scalar quantity and it is expressed using a number with appropriate units. The SI unit of resistance is Ohm Specific resistance or resistivity (ρ), of a conductor, is defined as the resistance of a conductor of unit length and unit area of cross-section.From the factors affecting the resistance of a conductor, the resistance is given by,Its SI unit is ohm-mSpecific resistance or resistivity is the characteristic property of the material of the conductor and depends only on the nature of the. COMBINATION OR A SYSTEM OF RESISTANCES (OR RESISTORS) The resistance can be combined in two ways: (i) In series, and (ii) In parallel. In Series: When two (or more) resistances are connected end to end consecutively, they are said to be connected in series. In Parallel: When two (or more) resistances are connected between the same two points, they are said to be connected in parallel An electric lamp of 100 Ω, a toaster of resistance 50 Ω and a water filter of resistance 500 Ω are connected in parallel to a 220 V source. What is the resistance of an electric iron connected to the same source that takes as much current as all three appliances and what is the current flows through it

So, new resistance is (1/16)th of original resistance. Class 10 Science Electricity Short Answer Type Questions[l] [2 Marks] - Year 2011. 33.A 9Ω resistance is cut into three equal parts and connected in parallel. Find the equivalent resistance of the combination. Answer When the values of L, the length, and A, the area is equal to one, we can say that the resistivity is equal to the resistance. So, resistivity is the specific resistance of a material. When we have a thick wire, the resistance decreases. The resistance increases when the wire is thin as the area of cross-section is less

Resistance increases and hence less electricity can pass through it Note - This is the reason that we use thick wire to carry more electrical load (as thick wire has more area of cross section and offers less resistance and more electricity can pass through it ) Nature of Material Resistance also depends on the nature of the materia Thin wire will have more resistance, since 2. Specific resistance of both wire is the same. Subject. Physics. Class. ICSE Class 10. Pre Boards. Practice to excel and get familiar with the paper pattern and the type of questions. Check you answers with answer keys provided. Sample Papers Electricity Class 10 Important Questions Short Answer Type II. Question 1. (a) Nichrome wire of length 'l' and radius 'r' has resistance of 10 Ω. How would the resistance of the wire change when: (i) Only length of the wire is doubled? (ii) Only diameter of the wire is doubled? Justify your answer Resistance of each and every conducting material is different for example but its range starts from 10^-8 but the two most used metal are Lithium 9.28 10 8 and iron 9.71 10 8

The lpotential at p is 10 v and varies uniformly along pq.What will be the potential at q? A battery of emf 3.0 V supplies current through a circuit in which resistance can be changed. A high resistance voltmeter is connected across the battery. When current is 1.5 A, voltmeter reading is 2.7V. Find internal resistance of battery. Current.
