Question

what current flows through a hair dryer plugged into a 112 volt circuit if it has a resistance of 27 ohms?
answer:
what are the units for your answer?
select one:
ohms
volts
amps

Explanation:

Step1: Recall Ohm's Law

Ohm's Law: $I = \frac{V}{R}$ where $V=112V$, $R=27Ω$

Step2: Calculate current

$I = \frac{112}{27} ≈ 4.15$

Step3: Identify unit of current

Current unit is amperes (amps)

Answer:

4.15
C. amps
