Question

calculating current
a wire with a resistance of 20 ω is connected to a 12 - v battery. what is the current flowing through the wire?
a

Explanation:

Step1: Recall Ohm's law

$I=\frac{V}{R}$

Step2: Substitute values

$V = 12\ V$, $R=20\ \Omega$, so $I=\frac{12}{20}$

Step3: Calculate the current

$I = 0.6\ A$

Answer:

$0.6$
