what is the current in a circuit with a 12.0 v battery and a 4.0 ω resistor?\n0.3a\n3.0a\n8.0a
what is the current in a circuit with a 12.0 v battery and a 4.0 ω resistor?\n0.3a\n3.0a\n8.0a
Answer
Explanation:
Step1: Recall Ohm's law
$I=\frac{V}{R}$
Step2: Substitute values
$I = \frac{12.0\ V}{4.0\ \Omega}$
Step3: Calculate the current
$I=3.0\ A$
Answer:
B. 3.0A
