a flashlight has a resistance of 2.4 ω. what voltage is applied by the batteries if the current in the circuit is 2.5 a?\n0.96 v\n1.0 v\n4.9 v\n6.0 v
Answer
Explanation:
Step1: Recall Ohm's law
$V = IR$ (where $V$ is voltage, $I$ is current, $R$ is resistance)
Step2: Substitute given values
$V=2.5\ A\times2.4\ \Omega$ $V = 6\ V$
Answer:
D. 6.0 V
