Hii There!!!
1) (Resistor) of "resistance R" :-
It reduces the amount of current flowing in a closed circuit.
2) Variable Resistance or Rheostat :-
It is a variable resistance in which we can increase or decrease the amount of current flowing through it by manually increasing or decreasing resistance.

Hope it helps☺️

nyzz attempt
Thanks...☺️
hey
In a series electrical circuit comprising of a resistor made up of metallic wire, ammeter reads 5A. The reading of ammeter decreases to half when the length of wire is doubled. Why
can u answer if u are genius
hehe
see I have given answer to your ques.
tanxx
ur wlcm ☺

Answer:
(1) first image is of resistor with resistance 'R'
its function is to resist the flow of current through the conductor
(2) second image is of the wire which are crossing without joining
it helps in taking wire from one place to another without joining with another wire
