Electric Current review

Electric current is

• Charge flow in a certain time

• Charge Flow by area

• Charge by distance

• Charge product by squared distance

Electric current is represented as

• A

• I

• E

• R

The unit to measure electric current is

• Coulomb

• Meter

• Volt

• Ampere

One ampere is

• A coulomb per meter

• A joule per meter

• A joule per coulomb

• A coulomb per second

Current divided by area is

• Charge density

• Current density

• Electric field

• Electric potential

Velocity for electric current is called...

• Drift velocity

• Electric potential

• Current area

• Current density

Single direction and constant current is

• Alternating current

• Direct current

Changing direction unlimited supply current is ...

• Alternating current

• Direct current

Ohm's law variables are

• Current voltage and charge

• Potential energy and distance

• Current voltage and resistance

• Voltage and electric field

Ohm's ñaw states that voltage is directly proportional to current and resistance so formula is

• V=I/R

• V= ER

• V=IR

• V= R/I
