Briana builds a circuit that has a resistance of 8.0 . What voltage should she apply to have a current of 0.8 A?

0.10 V
6.4 V
7.2 V
10 V

Respuesta :

The voltage is 6.4 V

Explanation:

We can solve this problem by using Ohm's law, which gives the relationship between voltage, current and resistance in a circuit:

[tex]V=IR[/tex]

where

V is the voltage

I is the current

R is the resistance

For the circuit in this problem, we have

I = 0.8 A (current)

[tex]R=8.0 \Omega[/tex] (resistance)

Solving for V, we find the voltage:

[tex]V=(0.8)(8.0)=6.4 V[/tex]
