2 SERIES CIRCUIT 3Ω3Ω 5Ω5Ω

3 V = RI V= VOLTS R = RESISTANCE I= CURRENT R = R 1 + R 2 BULBS ARE LESS BRIGHT BATTERY LAST LONGER IF ONE IS DISCONNECT, BOTH DON’T WORK 3Ω3Ω 5Ω5Ω

4 PARALLEL CIRCUIT 3Ω3Ω 5Ω5Ω

5 BULBS ARE BRIGHT BECAUSE ITS DIRECT TO THE SOURCE BATTERY DOESN’T LAST LONG IF ONE IS DISCONNECT, THE OTHER ONE STILL WORKS R = R 1 R 2 /R 1 + R 2 5Ω5Ω 3Ω3Ω
