[QUOTE="timetraveller, post: 6253, member: 456"] For those who care the heating effect with a DC current is I squared R where I is the current flowing and R is the resistance. So halving the current gives one quarter of the heating effect while conversely doubling the current give four times the heating. A faulty connector etc which introduces an extra resistance into a circuit gets hot. You knew that didn't you? Change from an original 6v 36 watt headlight passing 6 amps to a 12 volt 60 watt headlight and you have only 5 amps passing through the circuit. This gives a heating ratio of 36 to 25 i.e. about a third less heating. Go for a 130 watt bulb and you have 11 amps. 6 amps squared is 36 heating units and 11 amps squared is 121 meaning that you have about 3.4 times more heating. Decent cables and dip switches are needed. Just had a good day at the Pie and Pint and nice to see you all there. :) [/QUOTE]
