Printer
5. Which two devices are considered input devices ? (Choose two.) Biometric authentication device
Printer
Digital camera
Projector
Speakers
6. Which two form factors are commonly used to build a new computer ? (Choose two.)
BTX

7. A tehnician creates a simple circuit that has a 9 V light bulb attached to a 9 V battery. The power ouput of the light bulb is 100 W. Wich equation should be used to calculate how much current in amps is required to archive the full 100 W ouput from the 9V bulb ?
I=P/V = 100W/9V= 11.11A
I=P*V=100W*9V=900A
I=(P/2)*V=50W*9V=450A
I=P*2*V=100W*(9v+9v)=8100A
