Un circuito que contiene una batería de 6.0 V se conecta con un resistor de 81.0 Ω. Si después de media hora el voltaje de la batería disminuye a 4.5 V, cómo cambia la corriente en el circuito respecto al principio

AI = 0.019 A

Explanation:

The computation of the current change and the same compared to the staring is shown below;

I = v ÷ R

= 5v ÷ 81.0

I = 0.074 A

Now  

I = v ÷ r

= 6v ÷ 81.0

I = 0.055A

Now

I = 0.074A - 0.055A

AI = 0.019 A

The same would be considered
