Electricity and magnetism (12A)

Whose word abbreviation is the laser?

Static electricity

Current (áram)

circuit - áramkör

1. bulb
2. wire - drót
3. battery - áramforrás
4. switch - kapcsoló

resistance - ellenállás
unit of resistance is Ohm

battery has voltage
ammeter - áram erősség mérő
unit of current is ampere

Resistance         Voltage          Current

22,35 Ohm        65,29 V          2,92 A
22,35 Ohm        25,29 V          1,13 A


Ohm's law

R=U/I
Resistance is equal voltage divided by current.

DC - direct current - egyenáram
AC-  alternative current -  váltóram
