Expert Solution
Step 1 Introduction

Current is a quantity that is defined as rate of flow of charge through a conductor. Current is not a vector but a scalar quantity despite having a direction because it doesn't follow Parallelogram law of Vector addition. It is measure in unit Ampere. 

Ammeter is an instrument that is used to measure current. It is nothing but a very low amount of resistance connected parallel to the galvanometer as a shunt. The voltage drop across shunt is measured by the galvanometer which is calibrated to give you the value to current.
