Answer 1

Answer:

potential gradient=0.1

Explanation:

total resistance(R)= 10(r)+38+2=50

emf(E)=2 v

current (I)=E/R=2/50=1/25

potential difference across wire (V)=Ir=(1/25)*10

potential gradient=potential difference/length of wire=(10/25*4)=0.1

Answer 2

Answer:

potential gradient = 0.1

Explanation:

total resistance(R)=10(r)+38+2=50

emf(E)=2 V

current(I)=E/R=2/50=1=25

potential difference across wire(V) =Ir=(1/25)*10

potential gradient=potential difference/length of wire=(10/25*4)0.1
