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.
Is DC voltage and average voltage same?
no, dc volatage is a type of current direct current, ac is alternating current, average voltage could be any type of voltage ac or dc that maintains a constant rangeAnswerNo. A DC voltage is exactly equivalent to an AC rms-voltage. So, for example, 100 V (DC) is exactly equivalent to 100 V (AC rms). The average value of an AC waveform is zero.
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
AC circuit that contains both resistance and inductance will have a.The current and voltage in phase b.current will lead the voltage c.current will lag the voltage d.voltage will lag the current?
a. the current and voltage in phase
What are the dependent and independent variables in relationship between resistance and current at constant voltage?
dependent variable is current and independent variable is resisitance
What are independent and dependent sources?
An independent source is a source that produce constant currents and voltage. Dependent sources are voltage sources that depend on a voltage somewhere else in the network.
What is the difference between independent and dependent source?
Independent SourcesIndependent sources produce current/voltage at a particular rate that is dependent only on time. These sources may output a constant current/voltage, or they may output current/voltage that varies with time.Dependent SourcesDependent sources are current or voltage sources whose output value is based on time or another value from the circuit. A dependent source may be based on the voltage over a resistor for example, or even the current flowing through a given wire. The following sources are possible:Current-controlled current sourceCurrent-controlled voltage sourceVoltage-controlled current sourceVoltage-controlled voltage sourceDependent sources are useful for modelling transistors or vacuum tubes.
Is it possible to use source transformation to dependent voltage source?
Yes.Source transformation in dependent voltage source can be solved the same like independent voltage source
What is the independent dependent and controlled variables in making a circuit?
The independent variable is the component you change, such as the voltage or resistor value. The dependent variable is the component that changes in response to the independent variable, like the current or brightness of a light. The controlled variables are factors you keep constant, such as the type of wires or battery used.
Why an independent voltage source is made deactivated by shortening and an independent current source is made deactivated by open circuiting?
Short-circuiting an independent voltage source effectively sets its voltage to zero, deactivating it. Since current in a short circuit is maximized, this creates a situation where the voltage source cannot maintain its specified voltage. Open circuiting an independent current source prevents the flow of current, effectively deactivating it because without a complete path for current to flow, the current source cannot maintain its specified current output.
What is the voltage drop across a resistor of 300 kilo ohm?
What is the amount of current flowing through the resistor? Voltage drop is dependent on the current. Ohm x Amps = Voltage drop
What size wire for 250 v AC?
Wire size is not dependent on voltage - it is dependent on current. Please restate your question and provide the expected branch current.
Is high-voltage syndrome an example of static or current electricity?
it is an example of current electricity
What is the maximum current that can be drawn from a voltage source?
The maximum current that can be drawn from a voltage source is dependent on the impedance of that source, the impedance of the connections to the source, and the energy available from that source.
How does voltage drop related to impressed emf?
Voltage drop is resultant of IR ie current and the line resistance, not dependent on impressed emf
Difference between csi vsi and zsi?
vsi's output voltage is independent of load nature, but output current is depends on load nature. csi's output current is independent of load nature, but output voltage is depends on load nature.
