briana builds a circuit that has a resistance of 8.0 ω. what voltage should she apply to have a current of 0.8 a?\n0.10 v\n6.4 v\n7.2 v\n10 v
Answer
Explanation:
Step1: Recall Ohm's Law
$V = IR$ (where $V$ is voltage, $I$ is current, $R$ is resistance)
Step2: Substitute given values
$V=0.8\ A\times8.0\ \Omega$ $V = 6.4\ V$
Answer:
B. 6.4 V
