Question

an electrician is using the voltage formula ( v = ir ), where ( v = ) voltage, ( i = ) current, and ( r = ) resistance, to determine the amount of current running through a circuit. manipulate the formula to solve for current, ( i ).
( i=\frac{v}{r} )
( i=\frac{v}{r} )
( i = r - v )
( i = v + r )

Explanation:

Step1: Isolate \( I \)

Given \( V = IR \). Divide both sides by \( R \).
$$\frac{V}{R}=\frac{IR}{R}$$

Step2: Simplify

Simplify the right - hand side. Since \( \frac{IR}{R}=I \) (assuming \( R
eq0 \)).

Answer:

\( I=\frac{V}{R} \)
