Briana builds a circuit that has a resistance of 8.0 ohms. what voltage should she apply to have a current of 0.8 a?
a: 0.10 v
b: 6.4 v
c: 7.2 v
d: 10 v

B: 6.4 V

Explanation:

the relationship between voltage, current and resistance in a circuit is given by Ohm's law:

where

V is the voltage

R is the resistance

I is the current

In this problem, the circuit has a resistance of , while the current in the circuit is . Substituting the numbers into the equation, we can find the voltage:

b mirrors submit a iisner? e. for which optical devices does d sometimes have a positive value? o a a and b o b. a and c o c. b and d 0 d. b and cb

i think the answer is tomato juice? not entirely sure though
