Anticorruption

1. Two students perform the experiments on series and parallel feature of two assumption resisters R1 and R2 and plot the following V-I graphs. This of the two graphs flop represents the labels series and parallel. Justify your answer. 2. Two metallic conducting telegrams A and B of the same material are attached in parallel. Wire A has length l and radius r. outfit B has length 2l and radius 2r. Calculate the ratio of the alike(p) enemy in parallel combination and the resistance of the telegram A. 3. You are given two resistors of 5? and 20?, a battery of voltage 2.5 V, a key and an ammeter. Draw a tour of duty diagram of all given components such(prenominal) that ammeter gives a reading of 0.1 A. 4. The galvanic resistivity of few materials is given to a lower place in ?m. Which one of these materials has the highest electrical conductivity and which has the lowest? A (6.84x10-8), B (1.60x10-8), C (1.00x10-4), D (2.50x1012), E(4.40x10-5) and F (2.30x1017). 5. A ingredient of wire of resistance 20?

is drawn out so that its length is increased to twice its original length. Calculate the resistance of the wire in the naked as a jaybird situation. 6. Two resistors with resistances (i) 5 ? and 10 ? (ii) 10 ? and 15 ? singly are to be marryed to a battery of emf (i) 6 V, (ii) 12 V so as to receive a) minimum current flowing, b) maximal current flowing. a. How will you connect these resistances in each roll? b. Calculate the strength of heart current in the circuit in the two cases.If you necessitate to get a broad(a) essay, order it on our webs ite: Be! stEssayCheap.com
