ELECTRIC CURRENT • Electric Current is many capacity which flow every one time. 1A • Unit : Ampere • Measurer : Amperemeter • Pattern :

q I= t

I : Electric Current (A) q : Charge (C) t : Time (s)

VOLTAGE • Voltage is many energy which needed to move electric charge 2,5 V • Unit : Volt • Measurer : Voltmeter • Pattern :

w V= q

V

: Voltage (V)

W

: Electric energy (J)

q

: Charge (q)

RESISTANCE • Resistance is ratio between rate of voltage and electric current. • Unit : Ohm • Measurer : Ohmmeter • Pattern :

V R= I

Ω)

V

: Voltage (V)

I

: Electric Current (A)

OHM’S LAW “Electric Current which flow in Electric Resistor is comparable with Voltage between Resistor Points”

V=IxR

Electric Current is 10 Ampere Resistance is 4 Ohm Voltage?

Pattern : V = I × R

KIRCHOFF’S LAW I “Total of Electric Current which enter to a ramification is same with total of Electric Current which exit from ramification point” 10 A

5A 2A

ELECTRIC CONNECTION • Series Connection R1
