voltage is devided only in series circuit and is the same at the parallel circuit
In order for the load to be energized in a circuit with multiple switches in series, all the switches must be closed or in the "on" position. This is because switches in series function like an "AND" gate in digital logic, requiring all inputs to be true for the output to be true. If any one of the switches is open or in the "off" position, the circuit will be open and the load will not receive power. Therefore, all switches must be closed to complete the circuit and energize the load.
A circuit breaker must be reset to ON after a short circuit but does not need to be replaced. It depends on the type of CB. A fuse is also a circuit breaker and it needs to be replaced after a short circuit. Relayed circuit breakers have to be "picked up" after a dropout and need not be replaced as such.

A series circuit only has one loop

There must be a current through the bulb in order for it to glow.
No. For electrons to flow, you need a current.
True. The voltage rating of a fuse must be greater than the circuit voltage.

False. A closed circuit is a complete loop where electricity can flow continuously from the power source, through the components, and back to the source.
True.
do not use radios or cell phones within 25 feet of fuzes.

No. While it is true that one can measure current at any point in a circuit by breaking the circuit at that point and inserting the meter, not any meter will do it. One must use an ammeter to measure current.
