if a circuit has a voltage of 500 v and a resistance of 250 ω, what is the current? a 0.50 a b 2.0 a c 2.5 a d 5.0 a
Answer
# Explanation:
## Step1: Recall Ohm's law
$I=\frac{V}{R}$
## Step2: Substitute values
$V = 500\ V$, $R=250\ \Omega$, so $I=\frac{500}{250}$
## Step3: Calculate current
$I = 2\ A$
# Answer:
B. 2.0 A
