Galvanometer is a device used to detect an electric current.
<u>Explanation:</u>
A galvanometer is an electro mechanical instrument utilized for distinguishing and demonstrating an electric flow. A galvanometer fills in as an actuator, by creating a revolving redirection, in light of electric flow moving through a loop in a consistent attractive field.
Galvanometer is a gadget which is utilized to quantify electric flows. Note that the shunt obstruction must be low with the goal that greatest current goes through the shunt. Thus galvanometer can be utilized to gauge high flows.
Most computer devices are connected to the computer through port
Keyboard through usb port
Printer through usb port
Hand point device through usb port
Also computer equipped with LPT port for printers and COM port for additional devices like external modems e.t.c
