SERIES AND PARALLEL CIRCUITS

SERIES CIRCUIT

3Ω 5Ω

SERIES CIRCUIT

V = RI

V= VOLTSR = RESISTANCEI= CURRENT

R = R1 + R2

• BULBS ARE LESS BRIGHT• BATTERY LAST LONGER• IF ONE IS DISCONNECT, BOTH DON’T WORK

3Ω 5Ω

PARALLEL CIRCUIT

3Ω

5Ω

PARALLEL CIRCUIT

• BULBS ARE BRIGHT BECAUSE ITS DIRECT TO THE SOURCE• BATTERY DOESN’T LAST LONG• IF ONE IS DISCONNECT, THE OTHER ONE STILL WORKS

R = R1 R2/R1 + R2 5Ω

3Ω
