Why you take the conjugate of current in complex power?
In order to calculate the complex power of a circuit, the conjugate of current is used. The Vrms of the circuit is multiplied by the complex conjugate of the total circuit current.
Why is a voltmeter not placed inside the circuit?
The voltmeter is connected parallel to the circuit in order to measure the voltage drop across that circuit or sub-circuit. If you were to connect the volmeter series to the circuit, since it is a high impedance device, it would represent an effective open-circuit condition. You would see the voltage available to the circuit, but the circuit would not receive its intended current and it would not function. Contrast this with the ammeter, which you do place series to the circuit in order to measure the current flow through the circuit.
Can items in a series circuit be in any order?
Yes. The arrangement doesn't change the current through the circuit, or the voltage acrosss any individual component.
What is the purpose of fixed resistor?
To lower the voltage and amperage in order to better fit the needs of other components.
Characteristics of good acceptor circuit?
It needs to be in good working order. If there are any cracks or tears in it, then it might not work properly.
How is an ammeter connected in a circuit in order to read the current flowing in the circuit?
In series with the circuit and never in parallel. The reason being that it will cause the circuit total resistance to drop which will make the circuit draw excessive current. That's a short circuit actually.
Why must a circuit be closed in order for current to a flow?
A circuit must be closed in order for a current to flow because it helps keep a current flow pass. When the switch is closed on a circuit there is a constant flow. When the switches open the flow is disturbed around the circuit.

What are two of the main requirements that allow electric charge to flow in an electric circuit?
In order to have a valid electric circuit, two requirements must be met: there must be a potential difference within it (measured in Volts), and current must be flowing through it (measured in Amperes). That implies that the three basic blocks of a circuit are present - a power source (that defines the potential and supplies the current), conductors (which connect the power source to the load), and the load, which consumes current to do some work. Coincidentally, lack of a potential difference means that there are no charges "willing" to travel between point A and point B, which means that there is no current flowing from A to B (or otherwise), in regard to just these two measurement points. Of course, if you connect just your voltmeter to a battery, you will see a readout - that is because the voltmeter completes the circuit (and is doing some work for you), and since the circuit is complete, the current is flowing, and that implies a difference of potential.
What are to things needed in order for current to flow in a circuit?
voltage and ground
In order to flow electricity must follow what?
In order for a current to flow there must be a complete circuit.
Why electric current current exist if an electric circuit is broken?
well, current is the movement of free electrons so if you break a point in the wire you effectively stop the electrons from flowing as the electrons need to be touching each other in order to pass on energy or charge. The reason why if there is a gap in the circuit the electrons dont just jump it is because of resistance of air as the electrons in air are not free to flow they are not conduction electrons unlike in a metal such as copper wire.

The parts of a series circuit are wired one after another so the amount of curren is the?
There is no current at all in the series circuit until the last component is in place, and the order in which they're arranged in the series circuit has no effect on the magnitude of current.
What are the 3 basic features all electric circuits must have?
3 components ; voltage supply or battery connection wires or wiring a lamp bulb to indicate presence of current flow within the circuit when current is actually flowing within the wires.
In order to have current flow what must a circuit be?
the ciruit must be closed so it can move freely
