Anticorruption

1. Two students perform the experiments on series and parallel have of two given resisters R1 and R2 and plot the following V-I graphs. This of the two graphs by rights 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. equip B has length 2l and radius 2r. Calculate the ratio of the care enemy in parallel combination and the resistance of the conducting wire A. 3. You are given two resistors of 5? and 20?, a battery of electric potential 2.5 V, a key and an ammeter. Draw a tour of duty diagram of all given components much(prenominal) that ammeter gives a reading of 0.1 A. 4. The galvanising 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 parvenu situation. 6. Two resistors with resistances (i) 5 ? and 10 ? (ii) 10 ? and 15 ? severally are to be subsumeed to a battery of emf (i) 6 V, (ii) 12 V so as to adjudge a) minimum current flowing, b) maximal current flowing. a. How will you connect these resistances in each roll? b. Calculate the strength of replete(p) current in the circuit in the two cases.If you take to get a broad(a) essay, order it on our website: O rderEssay.net
