Answer to Question #162544 in Physics for Kly

Question

What is the resistance and power if a resistor is 0.6of current flows through it and voltage is 12V

Answer 1

We can find the resistance from the Ohm's Law:

$$R=\dfrac{V}{I}=\dfrac{12\ V}{0.6\ A}=20\ \Omega.$$

We can find the power as follows:

$$P=VI=12\ V\cdot0.6\ A=7.2\ W.$$
