Question

What power is emitted by a circuit with a 9.00 volt battery and a 50.0 Ohm resistor? A)450 W B)0.00222 W C)1.62 W D)5.55 W E)0.180 W

Answer 1

Given,

Voltage, V=9 V

Resistor, R=50.0 ohm

To find

The power emitted by the battery.

Step-by-step explanation

The power is:

`\begin{gathered} P=(V^2)/(R) \\ \Rightarrow P=(9^2)/(50) \\ \Rightarrow P=1.62\text{ W} \end{gathered}`

Conclusion

The power is: C.1.62W
