FREE Bachelor of Electrical Engineering Electric Circuits Questions and Answers
The element of an inductor is .
It is a passive element, which means it cannot produce electricity.
The ability of materials to obstruct the current flow is
Resistance is the ability of a material to oppose a current flow.
The fundamental measure of light intensity is
The candela, represented by the symbol cd, is the unit for luminous intensity.
What causes the current divide issue
Current differs from voltage when running in parallel.
When dealing with a dependent voltage/current source, its value is determined by .
A dependent voltage/current source is a type of source in electrical circuit analysis that is controlled by the voltage or current in another part of the circuit. Its value is determined by the voltage or current in a different component of the same circuit. This makes it different from an independent source, which provides a fixed value of voltage or current regardless of the rest of the circuit's conditions.
They are depending on some other source, as indicated by the name dependent. The amount of a voltage/current source present someplace in the circuit itself determines the value of a dependent voltage/current source. Which source in an ICVS is controlled and which one is dependent?
Current-controlled voltage source, or ICVS. Since voltage depends on current, it can be said that current is the controller and voltage is the dependent source (va=βia).
What justifies the current division?
In a parallel circuit, multiple components or loads are connected across the same two points or nodes. Each branch in the parallel circuit provides a separate path for the current to flow from the common point. The key characteristic of parallel circuits is that the voltage across all branches is the same (equal to the source voltage).
Positive power is defined as:
P > 0 means +ve Power Being delivered,P < 0 means –ve Power Being extracted.
Where the voltage division issue appears
Voltage and current are equivalent in series.
Which of the following corresponds to a specific quantity?
The seven established quantities—length, mass, time, electric current, thermodynamic temperature, amount of substance, and luminous intensity—are the foundation of the SI units.
The symbol used to indicate Unbiased sources
The symbol used for representing independent sources in electrical circuit diagrams is a circle. Independent sources are voltage sources or current sources that provide a fixed value of voltage or current regardless of the rest of the circuit's conditions. In circuit diagrams, an independent voltage source is represented by a circle with a plus sign (+) inside, while an independent current source is represented by a circle with an arrow inside. These symbols indicate that the source provides a specific, constant value of voltage or current independently of the rest of the circuit's elements.
The charge is
Due to the fact that it can be expressed as positive or negative, charge is bipolar.
The Superposition concept is upheld by .
The Superposition Principle is followed by a linear system. The parameters of a linear network are fixed, i.e., they don't change with voltage and current.
Which of the following relationships is correct?
Tera – 10¹², Giga – 10⁹, Mega – 10⁶.
What is dependent sources' alternate name?
Dependent sources are also referred to as controlled sources since they are under the control of other circuit components.
Dependent sources have been ____________ types.
There are four different categories of dependent sources. Current-controlled current/voltage sources and voltage-controlled current/voltage sources.
