Resistance of a Conductor Part 2
>> YOUR LINK HERE: ___ http://youtube.com/watch?v=b3vak7-3a40
Problem: • Calculate the resistance of 100 m length of a wire having a uniform cross-sectional area of 0.1 mm^2, if the wire is made of manganin having a resistivity of 50 × 10^−8 Ω-m. If the wire is drawn out to three times its original length, by how many times would you expect its resistance to be increased?","styleRuns":[{"startIndex":0,"length":310,"styleRunExtensions":{"styleRunColorMapExtension":{"colorMap":[{"key":"USER_INTERFACE_THEME_DARK","value":4294967295},{"key":"USER_INTERFACE_THEME_LIGHT","value":4279440147}]}},"fontFamilyName":"Roboto"}]},"headerRuns":[{"startIndex":0,"length":310,"headerMapping":"ATTRIBUTED_STRING_HEADER_MAPPING_UNSPECIFIED"}]}},{"itemSectionRenderer":{"contents":[{"continuationItemRenderer":{"trigger":"CONTINUATION_TRIGGER_ON_ITEM_SHOWN","continuationEndpoint":{"clickTrackingParams":"CMIBELsvGAIiEwiOj-2c96eKAxXogIwIHZ0bADs=","commandMetadata":{"webCommandMetadata":{"sendPost":true,"apiUrl":"/youtubei/v1/next"}},"continuationCommand":{"token":"Eg0SC2IzdmFrNy0zYTQwGAYyJSIRIgtiM3ZhazctM2E0MDAAeAJCEGNvbW1lbnRzLXNlY3Rpb24%3D","request":"CONTINUATION_REQUEST_TYPE_WATCH_NEXT"}}}}],"trackingParams":"CMIBELsvGAIiEwiOj-2c96eKAxXogIwIHZ0bADs=","sectionIdentifier":"comment-item-section","targetId":"comments-section"}}],"trackingParams":"CMEBELovIhMIjo_tnPenigMV6ICMCB2dGwA7"}},"secondaryResults":{"secondaryResults":{"results":[{"compactVideoRenderer":{"videoId":"bD0MDRcf14A","thumbnail":{"thumbnails":[{"url":"https://i.ytimg.com/vi/bD0MDRcf14A/hqdefault.jpg?sqp=-oaymwEbCKgBEF5IVfKriqkDDggBFQAAiEIYAXABwAEG rs=AOn4CLCGe8wA7VrP47Qx_WuOypt4uhlUPA","width":168,"height":94},{"url":"https://i.ytimg.com/vi/bD0MDRcf14A/hqdefault.jpg?sqp=-oaymwEcCNACELwBSFXyq4qpAw4IARUAAIhCGAFwAcABBg== rs=AOn4CLD03uec2FAe2PEYII6QWFPclnkNww","width":336,"height":188}]},"title":{"accessibility":{"accessibilityData":{"label":"Resistance of a Conductor Part 3 door Engr.
