Question

define 1 amphere? name the device which is used to measure electric current and how is it connected in an electric circuit ​

Answer 1

Answer:

An ammeter (from ampere meter) is a measuring instrument used to measure the current in a circuit. Electric currents are measured in amperes (A), hence the name. Instruments used to measure smaller currents, in the milliampere or microampere range, are designated as milliammeters or microammeters.

Explanation:

Answer 2

Device is ammeter. It is connected in series to measure current through it. 1ampere=when 1 ohm resistor allows cureent to flow in potential diff of 1v.
