Your 60-watt light bulb is plugged into a 110-volt household outlet and left on for 3 hours. of each kwh costs $0.11, about how much money does the energy company charge you?

A. The current in a 60-Watt bulb plugged into a 120-Volt outlet is 0.5 A.  

I = P / V = (60 W) / (120 V) = 0.5 A

Other answers:

b. The current in a 120-Watt bulb plugged into a 120-Volt outlet is 1.0 A.

I = P / V = (120 W) / (120 V) = 1.0 A  

c. The power of a saw that draws 12 amps of current when plugged into a 120-Volt outlet is 1440 W.

P = V • I = (120 V) • (12 A) = 1440 W

d. The power of a toaster that draws 6 amps of current when plugged into a 120-Volt outlet is 720 W.

P = V • I = (120 V) • (6 A) = 720 W

e. The current in a 1000-Watt microwave when plugged into a 120-Volt outlet is 8.3 A.

I = P / V = (1000 W) / (120 V) = 8.3 A

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )
