Question

help me in Q8 (c) please

Answer 1

internal resistance of a cell
is the resistance offered because of the chemicals present inside a cell

c. total resistance

resistance in parallel = 1/R = 1/2+1/6
= 2/3
R1= 3/2. (I)
R2= 2
R1+R2 = 3 /2+2 = 7/2

total R =7/2 +0.5 = 4 ohms


ii. WE KNOW
V=IR
I= V/R
=9/4 A
