Electromotive forceconductorsinternal resistancewhat is fuse and its function?
the SI unit of conductance is more commonly the siemens, but mho is also correct!
EMF (pretty much the same as electrostatic potential or voltage) is measured in units of energy per charge such as joules per coulombs (volts). Resistance is measured in ohms Appropriately enough, it's inverse, conductance, is measured in mhos. Because it's simply the inverse of resistance, conductance never really gets used. You just say 1/R instead. The function of a fuse is to burn out when current spikes so that more valuable components DON'T burn out or the circuits in the wall of your house don't catch fire or something very bad. It's rare to see fuses in a house now because circuit breakers do the same job and don't have to be replaced after tripping.
