AS WE KNOW RESISTANCE OF WIRE DEPENDS DIRECTLY ON ITS LENGTH AND INVERSLY ON ITS AREA OF CROSS SECTION
SO IF THE WIRE IS CUT INTO THREE EQUAL PARTS AND CONNECTED IN PARALLEL WE WILL FIND ITS EQUIVALENT RESISTANCE
AS WE KNOW THE RESISTANCE 9F WIRE IS GREATER IF CONNECTED IN SERIES SO THE RESISTANCE WILL DECREASE
ALSO RESISTIVITY IS CONSTANT PROPORTIONALITY
