I'm not sure how in detail you want this response to be.

But literally, connect a wire to the ground. It should run from the current-carrying wire of the appliance to the ground. Or something that is in contact with the ground.

Assuming the residence has wiring that is compliance with NEC the outlet will have a three wire receptacle, in the U.S. it will be 2 rectangular openings and a round opening.  It is the round opending that has the "ground" wire which goes all the way back to the service pane and then to an earth ground along with the neutral connection.   The plug that mates with that receptacle should have three separate wires. One white, one black, and one green, the green being the ground. On the opposite side that goes to the appliance, the green must connect to a green screw or terminal connected to the chassis/cover/case. When so connected the user is protected from a fault in insulation or wiring that would cause the chassis/case/cover etc. to become "hot" If the wiring is old and only provides the two wire receptacle a new GFCI type receptacle can be installed. This device monitors the current in each of the two wires (line and neutral) and if they differ by 5 milliamps the line is interrupted. This unbalance could occur when a fault occurs that provides a path shunting neutral because of line leaking to the case/chassis/cabinet etc.
