Question

solve for missing
e = 12 volts
i_t = ______
r_t = 3 ohms
○ 4 volts
○ 4 amperes
○ 9 amperes
○ 3 amperes

Explanation:

Step1: Recall Ohm's Law

Ohm's Law states that \( I = \frac{E}{R} \), where \( I \) is current, \( E \) is voltage, and \( R \) is resistance.

Step2: Substitute the given values

We know \( E = 12 \) volts and \( R_T = 3 \) ohms. Substitute these into the formula: \( I_T = \frac{12}{3} \).

Step3: Calculate the result

\( \frac{12}{3} = 4 \). The unit for current is amperes, so \( I_T = 4 \) amperes.

Answer:

4 amperes (corresponding to the option: 4 amperes)
