A switch is inserted into a series circuit of Christmas lights. During the night, the switch is left open.
The lights will
continue to burn
be turned off
become a parallel circuit
The flow of electricity through a circuit can be compared to the flow of water through a pipe. Using
this comparison, the friction caused by the pipe wall would be similar to
the resistance in the circuit.
the amperage of the circuit.
the voltage of the circuit.
the magnetism of the circuit.
In a closed circuit.
electricity will flow.
electricity will not flow.
electricity creates voltage.
a negative terminal does not exist.
