section2 electric energy resistance and power

The symbol for …………..is P, it is measured in Watts ( …..).

• power .... J

• current ....W

• power.....W

• resistance..... ohms

The symbol for current is …., it is measured in ………………( A).

• I...current

• I......ampere

• ampere........I

• non of the above

The symbol for resistance is , it is measured in Ohms ( ).

• true

• false

superconductor

• material with high resistance

• material with low resistance

• material with half resistance

• material with zero resistance

kWh stand for

• kilowestohm

• kilometwer

• kilowatt hour

kilowatt hour is equa to

• 1000W for 3600s

• 1500W for 3600s

• 1000W for 3000s

• 500W for 10s

this is

• power device

• smartmeter

• kilowatt hour device

electric energy can be transformed to

• radiant energy

• thermal energy

• mechanical energy

• all of the above

electrical energy is transformed into thermal energy whenever moving charge transfer energy to other particals

• true

• false

• i don`t know:)
