Answer 2

Answer:

R=12Ω , V1-V2=36

Explanation:

Concept

• According to Ohm's law, the voltage or potential difference between two locations is proportional to the current or electricity going through the resistance, and the resistance of the circuit is proportional to the current or electricity traveling through the resistance. V=IR is the formula for Ohm's law. Georg Simon Ohm, a German scientist, discovered the link between current, voltage, and relationship.

Solution

$V1-V2=IR\\V1=Potential Difference\\I=Current\\R=Resistense$

$Where I=3\\R=R1+R2+R3=3+4+5$

R=12Ω

V1-V2=3*12=36
