Answer 1

Explanation:

a, an instrument for measuring the strength of an electric current

b, an instrument for measuring voltage

c, an electric current is a stream of charged particles such as electrons or ions , moving through a conductor or space

d,an instrument used to control a current by varying the resistance

e, resistivity is a fundamental property of a material that measures how strongly it resists electric current

f, variable resister is a resister of which the electric resistance value can be adjusted
