What else can I help you with?
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 does it mean to have a power factor of 1?
First we need to know what is power factor ? it's cosine of angle between the current and voltage at that point where we wish to measure it. so power factor of "1" means the angle between the voltage and current is 0 degree. It means literally that the current and voltage is in the same phase.
What is the relationship between voltage and current in electrical systems, specifically, does high voltage necessarily mean high current?
In electrical systems, voltage and current are related by Ohm's Law, which states that voltage equals current multiplied by resistance. Therefore, high voltage does not necessarily mean high current, as the current also depends on the resistance in the circuit.
What mean by va in current transformer?
Its simply multiplication of voltage applied and current.
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)
How do I calculate wattage?
To calculate wattage, you need to multiply the voltage (V) by the current (I). The formula is: Wattage (W) = Voltage (V) x Current (I). This formula applies to electrical circuits where the voltage is known and the current is flowing.
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 a relationship among voltage current and resistance in a circuit?

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 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 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.
How do you convert arms to watts?
To convert arms (root mean square current) to watts (power), you need to know the voltage in the circuit. The formula for this conversion is: Power (W) = Current (Arms) x Voltage. Multiply the root mean square current (Arms) by the voltage in the circuit to get the power in watts.
What is the relationship between voltage and current as shown in the graph of voltage vs current?
In the graph of voltage vs current, the relationship between voltage and current is linear. This means that as voltage increases, current also increases proportionally.
