cation
anion is negatively charged, so more electrons then protons,
cation is positively charged, so more protons thatn electrons
Answer:
U = - 4 x 
Explanation:
ΔV = potential difference = 
Volts
q = charge on electron = 
C
electric potential energy is given as
U = q ΔV = ( ) ( )
= - 4 x

Answer:
8 ohms
Explanation:
The two resistors of 2 ohms each are connected in parallel so their equivalent resistance becomes
2*2/2+2=4/4=1 ohm
Now this 1 ohm resistance is in series with the other two resistors
Therefore resultant resistance becomes
3+1+4=8 ohms
