Ammeter A1 reads 0.4 amps. A2 also reads the same... What happens to the values of the ammeter if the LDR was covered over (put in the dark)?

• Both ammeter readings increase

• Both ammeter readings decrease

• Both ammeter readings stay the same

• Ammeter A1 decreases

• Ammeter A2 decreases

Why are SERIES circuits bad?

Select the two correct answers

• More electricity is pushed out

• Less electricity is pushed out

• Bulbs are dimmer

• Bulbs are brighter

• If one bulb blows, the circuit stops

Why are PARALLEL circuits bad?

• More electricity is pushed out so the cells run out sooner

• Less electricity is pushed out

• Bulbs are dimmer

• Bulbs are brighter

• If one bulb blows, the circuit stops
