i Have the bulbs been connected to the battery
in series or in parallel?
ii What is the reading on voltmeter Z? Give a
reason for your answer.
iii If one of the bulbs is removed, so that there

Answer 1

Answer:

When a bulb in a series circuit is unscrewed all bulbs in the circuit go out. Increasing the number of bulbs in a series circuit decreases the brightness of the bulbs. ... Bulbs in parallel are brighter than bulbs in series. In a parallel circuit the voltage for each bulb is the same as the voltage in the circuit.
