What does the electronic term Vb mean?
Base voltage in a transistor. There is also Vc (Collector voltage), Ve(Emitter voltage), Ic(Collector current), Ib(Base current), Ie(Emitter current), Vcc(Supply voltage), and Hfe (Forward current gain)
What is the relationship among voltage current and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
When voltage increases what happens to current?
Ohm's law states that "The current is directly proportional to the applied EMF (voltage) and inversely proportional to the resistance in the circuit."AnswerIf the voltage across a circuit increases, then the current will increase too. If the ratio of voltage to current is constant for variations in voltage, then the circuit is described as being 'linear' and is obeying Ohm's Law; if the ratio of voltage to current changes (as it would, for example, with tungsten) for variations in voltage, then the circuit is described as being 'non-linear', and is not obeying Ohm's Law. This is because Ohm's Law is not universal, and only applies to certain materials; in fact, most materials and electronic devices do not obey Ohm's Law.
Why current leads in capaciter?
Capacitors resist a change in voltage. It takes current to effect a voltage change, resulting in the current "leading" the voltage. Similarly, inductors resist a change in current. It takes voltage to effect a current change, resulting in the current "lagging" the voltage.
What is the formula of electric current?
the formula for electric current is VI ,where v is voltage then I is the current. the unit used for current is ampere and volts for voltage. multiply the total I to the Voltage The formular of electric current is given by I=V/R ,I=P/V
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).
Are Voltage and Current two important components to robotics?
Voltage and current are important parameters in any electrical and electronic devices and apparatus, including robotics.
What does the electronic term Vb mean?
Base voltage in a transistor. There is also Vc (Collector voltage), Ve(Emitter voltage), Ic(Collector current), Ib(Base current), Ie(Emitter current), Vcc(Supply voltage), and Hfe (Forward current gain)
Why you are using rectifiers in electronic circuits?
To convert voltage to DC .*(Direct Current)
What is electronic breakdown?
Most electronic devices have maximum voltage or current ratings, so if you exceed these maxima, you can expect them to breakdown...ie: Malfunction. Most breakdowns are permanent, so removing the excess voltage or current will not cause them to recover.
Why galvanometer are used in electronic instruments that measures low current and voltage?
The galvanometer is very sensitive.
What is Difference Between Current Source and Voltage Source?
A current source varies the output voltage to maintain the desired current. A voltage source has a constant output regardless of the current draw (up to the capacity of the supply, of course).
If you double both the voltage and the resistance in a circuit what would be the effect on the current?
If you double the voltage in a circuit, the power is quadrupled, assuming the resistance stays the same.
Definntion of active elements?
An active electronic element is one that can produce voltage gain or current gain.
Modern electronic multimeter measures resistances by?
forcing a constant current and measuring the voltage across the unknown resistor.
What is Passive linear bilateral network?
If I divide the term into words as (Passive + Linear + Bilateral ) Network then it would be easier to understand. 1st of all, Passive Network is a network that includes **passive electrical / electronic components. Then, Linear Network is consists of passive electrical / electronic components whose parameters such as resistance, capacitance or inductance are constant with respect to current or voltage and in such network each voltage or current source act independently of each other. After that, Bilateral Network is the network in which the magnitude of current remains the same when the voltage polarity is reversed. So, A Passive linear bilateral network includes passive components that exhibit linearity and at the same time magnitude of current is independent of the polarity of voltage. ** Passive electronic components are Resistor, Inductor or Capacitor, they by themselves are not capable of amplifying or processing an electrical signal.
