The simplest form of an electrical circuit is when an energy source (such as a battery) is connected to a load (such as a light bulb or a resistor). The connections must be made in such a way as to allow the energy to flow from the source, through the load and back into the source to form a loop.

FranWhat is probably the most fundamental circuit is one called a series circuit. It might be like a flashlight. In this simple series circuit, there are batteries (cells) and a lamp and a switch, plus the wiring. The defining characteristic is that there is one and only one path for current flow. All the current in the circuit must pass through each part of the circuit. A single break anywhere in the circuit will stop current flow.

If an electric circuit is not grounded it is best to reach out and touch it to provide the ground?
No. Touching a live electric current is never a good idea.
True or false in a series circuit circuit current is the same throughout the circuit?
A series circuit only has one loop
True or false switches can control each branch in a parallels circuit separately?
true
What is true about the sum of the voltages across the components in a circuit compared to the voltage of the cell?
voltage is devided only in series circuit and is the same at the parallel circuit
Is it true or false that a circuit breaker must be replaced after a short circuit occurs?
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.
