Coil as a girl

The electrical resistance of the copper wire coil is 2.0 ohms. What current runs through the coil when the voltage between the terminals is 3.0 V?

Result

I =  1.5 A

Solution:

$R = 2 \ Ω \ \\ U = 3 \ V \ \\ I = U/R = 3/2 = \dfrac{ 3 }{ 2 } = 1.5 = 1.5 \ \text{ A }$

Our examples were largely sent or created by pupils and students themselves. Therefore, we would be pleased if you could send us any errors you found, spelling mistakes, or rephasing the example. Thank you!
