In summary, a series circuit is defined as having only one path through which current can flow. From this definition, three rules of series circuits follow: all components share the same current; resistances add to equal a larger, total resistance; and voltage drops add to equal a larger, total voltage.
What are the requirements for an electric circuit?
To produce an electric current, three things are needed: a supply of electric charges (electrons) which are free to flow, some form of push to move the charges through the circuit and a pathway to carry the charges. The pathway to carry the charges is usually a copper wire.
What two things must an electric circuit have?
All electric circuits have at least two parts: a voltage source and a conductor. They may have other parts as well, such as light bulbs and switches, as in the simple circuit seen in the Figure below. The voltage source of this simple circuit is a battery.
What are the two requirements of a circuit?
There must be an energy source (battery) capable of doing work on charge to move it from a low energy location to a high energy location. This establishes a potential between the two ends of an electric circuit. 2. There must be a closed conducting loop that connects from the high potential to the low potential.
What is difference between network and circuit?
An ‘electrical network’ is an interconnection of electrical elements such as resistors, inductors, capacitors, transmission lines, voltage sources, current sources, and switches. An Electrical circuit is a network which has a closed path that gives the return path for the flow of current.
What is load switch?
A load switch is an electronic component that has no moving parts, which works somewhat like a relay. Generally, two MOSFET transistors act like a switching element, one of them being an N-channel device, and the other a P-channel device.
