1.	A wire of resistance R is cut into five equal parts. These parts are then connected in panllel If the equivalent resistance of this combination is R'. Calculate the ratio R/R'. Draw a clrcuit diagram to show two resoton R_(1) and R_(2) connected In parallel along with a battery, by, ammeter and voltmeter.
Answer» Solution :RESISTANCE of each PART = R/5 When connected in parallel : `(1)/(R) = (5)/(R)+(5)/(R) +(5)/(R)+(5)/(R) +(5)/(R) = (25)/(R)` `:. (R)/(R) = 25 `
