Question

When an electric appliance is connected to a 120 V power line, there is a current through the appliance of 60mA. What is its resistance?

Answer 1

Answer:

$2 ~k \Omega$

Explanation:

Use Ohm's law

$V = IR$

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

$R = \dfrac{120}{60 \cdot 10^{-3}} = 2 \cdot 10^3 ~\Omega$
