Answer:

For a 470-Ohm resistor connected to a 9-votl battery the current that will flow is 0.019A or 19mA

Explanation:

Ohm's law states that the voltage v along a resistor is directly proportional to the current i flowing through the resistor.

[tex]v = i R[/tex]

Clear i from the equation above

[tex]i = \frac{v}{R}[/tex]

[tex]i = \frac{9volt}{470ohm} =0.019A[/tex]
