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 does the continuity of capacitor voltage mean?
It might mean that the voltage across a capacitor cannot change instantanteously because that would demand an infinite current. The current in a capacitor is C.dV/dt so with a finite current dV/dt must be finite and therefore the voltage cannot have a discontinuity.
What is the relationship among voltage current and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
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 mean by va in current transformer?
Its simply multiplication of voltage applied and current.

What is term used when an Alternating current acts like a direct current?
Perhaps you are asking how the voltage of alternating current is measured, to be equivalent to the voltage of a direct current system. Alternating current and direct current have distinct properties. With direct current, voltage is at a constant polarity, and a direct current voltage source will maintain a uniform, constant voltage level. Alternating current reverses polarity at a given frequency and therefore it's voltage continuously varies from a positive peak voltage level, through zero, to a negative peak voltage level, repeating this cycle continuously. For this reason, voltage of an alternating current system, is measured in root-mean-square (rms), which is a voltage, which when multiplied by the current in amperes, calculates power which is equivalent to that of direct current of the same voltage and current values. With a typical sinusoidal waveform, the peak voltage of alternating current is divided by the square root of 2 to determine the rms voltage. The 120 volts output in the wall outlet in our home is actually about 170 peak volts.
Can there be a current with no voltage?
No, There can't Be current without voltage
How does voltage produce current?
Voltage across two terminals mean there exists a potential difference, and when the circuit gets closed, due to this potential difference the current flow.
What is the relationship among voltage circuit and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
What is AC voltage terminology - in phase - mean?
If the current rises and falls with the voltage, then the two are said to be 'in phase'; this occurs in a purely-resistive circuit. For inductive or capacitive circuits, the current either lags or leads the voltage.
What is 10000 rms?
rms stands for root mean squared. rms voltage is a way of measuring a sort of average alterating current voltage as distinguished from peak-to-peak voltage. Likewise for ac rms current.
What is powerful mean?
The product of the instantaneous voltage and the instantaneous current for a circuit or component.
