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.
What 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.
Are Charges in an electric circuit flow because of a difference in electrical potential energy true or false?
TRUE
Which of the statements concerning parallel circuits is NOT true?
D. The total resistance is equal to the lowest resistance in the circuit
True or false are charges in an electric circuit flow because of a difference in electrical potential energy?
True. Charges in an electric circuit flow because of a difference in electrical potential energy. This difference causes the charges to move from areas of higher potential energy to areas of lower potential energy, thus creating an electric current.
Does a battery operated toy have a parallel circuit?
Yes, a battery operated toy has a parallel circuit - the battery is in parallel with the toy. In fact, this is true for any system where there is a single equivalent source and a single equivalent load. While it is true that this is also a series circuit, by Kirchoff's current and voltage laws a simple series circuit is also a simple parallel circuit.
Can electromagnets be turned off by opening an electric circuit?
True.. Yes, they operate by turning the current on and off
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.
Can you fix a broken electric circuit?
no. you can not fix a broken electric circuit because the wires inside of it would be to badly damaged...and yupperz...your welcome...im bored..im in Friday night scholl:(((..but yeah that's true
Is it true that in a series circuit electric currents flow through more than one path?
more than 1
In an electric circuit the ground prevents current from flowing in the circuit true or false?
In an electric circuit, the ground does not prevent current from flowing. Instead, it provides a safe path for electrical current to return to the earth in the event of a fault. It's a protective measure to prevent electrical shock hazards by maintaining the voltage stability in the circuit. The normal operation of the circuit isn't affected by the grounding system.
Is it true that electric charges can flow through any of the pathways in a parallel circuit?
Yes, in a parallel circuit the electric charges have multiple pathways to flow through. This means that each component in the circuit will have its own separate pathway for the charges to travel through, allowing for different currents to flow through each branch of the circuit simultaneously.
Does it make any difference which way you hold the material in the circuit?
Indeed the order and position are vital to the performance of an electric circuit. This is even true for house wiring. (A switch should be before a lamp, not after, and so on.)
True or false in a series circuit circuit current is the same throughout the circuit?
A series circuit only has one loop
