What are the rules in series circuit?
Kirchoff's Current Law: The current at every point in a series circuit is the same. This can also be expressed as the sum of the currents entering a node is zero. Kirchoff's Voltage Law: The sum of the voltage drops across all elements in a series circuit add up to zero.
Which configuration of bipolar junction transistor which will give both current gain and voltage gain?
high voltage gain :- common base since the ratio of output impedance to the input impermanence is very high in common base mode high current gain :-common collector since it is the ratio of Ie/Ib
Lrc parallel circuit?
LRC parallel circuit contains its component in parallel connectio. It contains inductor, resistor and a capacitor. A parallel circuit is a closed electrical circuit in which the current is divided into two or more paths and then returns via a common path to complete the circuit
Why emitter follower is used in circuits?
The (Class C, Common Collector) Emitter Follower is used to amplify the available current from a voltage driving circuit that might be disturbed by the load impedance. If the actual voltage value is important, the emitter follower is often teamed up with an opamp which sets the emitter voltage based on the input voltage.
What are four characteristics of parallel circuit?
an example would be thus. if you had say 2 1.5 volt batteries each say .006 amps. When these batteries are in series the positive end of one is in contact with negative end of the other, pretty much like a common flashlight, and the voltage would be 3 volts., .006 amps. When the same two batteries are connected negative to negative and positive to positive the voltage would still be 1.5 volts but the amperage would be .012 amps. (amps doubled when in parallel, voltage doubled when in series)
How do parallel circuits use current and voltage?
Kirchoff's voltage law: In a series circuit, the signed sum of the voltage drops around the circuit add up to zero. Since a parallel circuit (just the two components of the parallel circuit) also represents a series circuit, this means that the voltage across two elements in parallel must be the same.Kirchoff's current law: The signed sum of the currents entering a node is zero. In a series circuit, this means that the current at every point in that circuit is equal. In a parallel circuit, the currents entering that portion of the circuit divide, but the sum of those divided currents is equal to the current supplying them.

What does resistro do?
resistors is a most common electronic component and is used to control the voltage and current in a electronic circuit. resistors is inversely proportional to amount of power supplied,given by (power= voltage *current).
What is more is correct v is proportional to i or i is proportional to v?
The induced current is proportional to applied voltage. i is proportional to v Or you might say, "A current source drives a fixed current through a circuit. Then the voltage developed is proportional to i" . Both forms are equally correct. Voltage sources are more common than current sources so the first form is more common.
How to compute watts to amps single phase?
In a single-phase system, power (expressed in watts) is generally called 'true power' or 'active power', and is the product of the supply voltage, load current, and load power factor.
What is the difference between series circuit and a parallel circuit?
For parallel circuit , each & every component shares 2 common connections . But for series circuit , each of them share 1 common connection .In electrical , each component has their own amount of current flowing through ( depending on the resistance of each ) and sharing the same voltage drop for parallel circuit . In case of series circuit , each component shares the same amount of current with each other & the voltage drop across each of them is different ( depending on their resistance ) .

What is the difference between common base emitter transistor and common base transistor?
Common base transistor if the emitter is open current Ie=0 but a small collector current thus exist.this current is reversed biased collector to the base voltage it is represented by Icbo while common emitter is d base terminal is open circuit and the base junction is reversed biased current Icbo flow from the tcollector to the emitter in the external circuit this current is called leakage current.
What is the difference between parallel and series?
If you are referring to an electrical circuit, a series circuit is wired in such a way that if one object is removed from the circuit, the circuit is broken and everything within the circuit loses power. In a parallel circuit different components of the circuit can be removed without disabling power to the rest of the devices within the circuit.
What configuration will give both voltage and current gain simultaneously?
amplifiers operated with Common emmitter configuration for bipolar transistors , will give both voltage & current gain . Though equivalent fet & mosfet circuit topologies exist , these amplifiers operate more on signal voltage on input & the signal current is negligible compared to a bipolar transistor.
Why do you use resistors and capacitors in a circuit?
resistors and capacitors are used in order to create a path for the current , for the resistivity of the current , for the storage of the current.AnswerResistors don't just 'resist' electric current, they create a predictable change in voltage (electric potential) from one side to the other, so they can be used to adjust the expected voltage level at each point in a circuit.In an electric circuit with an unchanging current and voltage, capacitors simply store current and wait for something to change.In the more common electronic case of a circuit with voltage fluctuations, each capacitor is effectively a high-pass filter -- it permits quickly-fluctuating voltages to pass through, but reduces or stops slowly-fluctuating voltages.
