ohm's law (v,i,r)

V=IR

OHM’S LAW FORMULA

A

UNIT OF ELECTRIC CURRENT (I)

CURRENT

IS THE RATIO OF ELECTRIC POTENTIAL ACROSS THE CIRCUIT ELEMENT TO THE RESISTANCE

I=V/R

CURRENT (I) FORMULA (FROM OHM’S LAW)

1C/S

1 AMPERE IS EQUALS TO

1C=1A*S

1 COULOMB HAS AN SI UNIT OF

CURRENT

IS THE RATE OF FLOW OF ELECTRIC CHARGE

VOLTAGE

IS THE ENERGY PER UNIT CHARGE

V

UNIT FOR VOLTAGE

VOLTAGE

THE PRODUCT OF RESISTANCE AND CURRENT

V=A*R

VOLTAGE FORMULA (FROM OHM’S LAW)

V=KG*M2/A*S3

VOLTAGE SI UNIT

RESISTANCE

IS THE OPPOSITION TO THE FLOW OF CURRENT

RESISTANCE

CAUSED BY THE COLLISIONS BETWEEN ELECTRONS AND ATOMS

OHM

RESISTANCE UNIT

RESISTANCE

IS THE RATIO OF ELECTRIC POTENTIAL ACROSS THE CIRCUIT ELEMENT TO THE CURRENT

R=KG*M2/S3*A2

RESISTANCE FORMULA (FROM OHM’S LAW)

HIGHER

THE GREATER THE RESISTANCE, THE LOWER OR HIGHER THE VOLTAGE IT REQUIRES

OHM’S LAW

RELATIONSHIP WHICH DESCRIBES THE MANNER IN WHICH ELECTRIC CURRENT BEHAVES IN AN ELECTRIC CIRCUIT
