Answer:
A.why does the circuit work even if the bulb is replaced with the buzzer and the bell
ANSWER
As more and more light bulbs are added, the brightness of each bulb gradually decreases. This observation is an indicator that the current within the circuit is decreasing. So for series circuits,
as more resistors are added the overall current within the circuit decreases.
B.why doesn't the circuit work when the jointed wire is replaced with an unjointed wire?
ANSWER
Unjointed wires does not allow the current to flow that is why the circuit will not work. Switch opens and closes the circuit but it can still work even without it.
C.why doesn't the circuit work when the switch is turned off
ANSWER
When the circuit switch is off, no electricity will flow and then the circuit is called an open circuit. Electricity will not flow in open circuit.
D.removing the switch ang connecting the two wires instead make the circuit still work?why?
ANSWER
Because a parallel circuit has more than one circuit for the current to flow, removing a lighbulb will only cause one circuit to be open. The other circuits remail closed and complete so the current can continue to flow. In a circuit, which part is the resistor?
