We can solve the problem by using Ohm's law, which states that an Ohmic conductor the following relationship holds:

where

is the potential difference applied to the resistor
I is the current flowing through it
R is the resistance
In our problem, I=4.00 A and

, so the potential difference is
Batteries Produce DC current while homes produce AC current.
Hope this helped xxxx
I would say the plastic grip because glass, wood, and plastic are all good conductors of electricity
