the lower and upper fixed points of a Mercury in glass is thermometer are marked Y and 180mm respectively. On a particular day the mercury meniscus in the thermometer rises to 45mm. If the corresponding reading on a celsius scale is 10 degree celsius, calculate the value of Y

Idont understand the question

Following the american gauge wire standards ,the larger gauge number, the slimmer the wire and thus the smaller current carrying capacity it can have.then both statements would be incorrect, as they are saying the opposite of what it is actually is.(smaller gauge numbers have thicker wires and can carry more current)
