Explanation:
The voltage of the battery in your car is always 12 to 13.5 volts. It makes no difference whether the car is home in the garage or zooming down the interstate.
<u>Explanation</u>:
Resistivity of silver wire =
Resistivity of copper wire = 
Resistance = Resistivity *length/cross sectional area
So,
For E calculation
For copper
E = resistivity * current density
E = Resistivity * current/area
For silver
Potential difference 
For silver
Potential difference = 
For copper
Potential difference =
Answer:
Personally, I am sure that learning everything by looking at image is more effective than looking at a forest of letters. As for the field of science as human biology, it is very very important as well, because the illustrations are vital resource to convey important medical information that is easier to understand by showing it as a drawing rather than by only describing it with text.
