In a series circuit, the current at every point in the circuit is the same. This is a consequence of Kirchoff's Current Law, which states that the signed sum of the currents entering a node must equal zero. Since a series circuit consists of nodes with only two elements connected to each node, it follows that the current at every point in a series circuit is the same.

State Kirchoffs voltage and current law?
Kirchoffs Current Law : [KCL]This law is also called Kirchhoff's point rule, Kirchhoff's junction rule (or nodal rule), and Kirchhoff's first rule. The principle of conservation of electric charge implies that: : At any point in an electrical circuit that does not represent a capacitor plate, the sum of currents flowing towards that point is equal to the sum of currents flowing away from that point. Kirchoffs Voltage Law : [KVL]This law is also called Kirchhoff's second law, Kirchhoff's loop (or mesh) rule, and Kirchhoff's second rule. : The directed sum of the electrical potential differences around any closed circuit must be zero.Kirchoffs Laws are widely used in the Electrical and Electronic engineering fields.Hope this helps =)
What is the total resistance in a parrellel ciruit?
The rule for finding total resistance in a parallel circuit is that a parallel circuit has two or more paths for current to flow through. Another rule states that voltage is the same across each component of the parallel circuit. If one of the parallel paths is broken, current will still continue to flow in all the other paths.
What simple rule has been established for finding the direction of magnetic force around a current-carrying conductor?
The right hand rule. If you were to place your right hand around the conductor, with the thumb pointing in the direction of current flow, your fingers which are wrapped around the conductor will point in the direction of magnetic flux. Said another way, if you are looking at the end of the conductor and current is flowing towards you, then magnetic flux will be counter-clockwise.
How the direction of EMF depends on the direction of current?
Current flow is from positive to negative. Use the left hand rule for finding the north and south poles. Grab the coil in your left hand, with your fingers wrapped around the coil in the direction of the current flow. Your thumb will then point toward the north pole of the coil. Reverse the positive - negative connections to the coil and the north - south poles will change ends. The left hand rule will still be in effect as the current will now be flowing in the reverse direction as it was in the first connection.
Why the voltage drop across inductance and voltage drop across capacitance is greater than source voltage in series resonance circuit?
The reason for the total voltage drops across the capacitance and inductance IN AN AC CIRCUIT has to do with the different phase angles of the voltages.First, current is the same value and same phase angle everywhere in a series circuit. But, voltage across a capacitor lags current by 90 degrees (capacitor current leads voltage). Next, voltage across a pure inductance leads current by 90 degrees (inductor current lags voltage).The rule that all voltages in a series circuit have to add to the supply voltage still applies, but in this case, the voltage drops are added VECTORALLY, not arithmetically. If you were to graph this addition, you would show any resistance voltage in phase with the current, the capacitor voltage at -90 degrees to the current and the inductor voltage at +90 degrees to the current, for a phase difference between them of 180 degrees, cancelling each other out.In a series resonant circuit, the impedances of the capacitor and inductor cancel each other. The only impedance to the flow of current is any resistance in the circuit. Since real-life inductors always have some resistance, at least there is always some resistance in a series resonant circuit.

Current in a parallel circuit?
In any parallel connection The original current gets divided into the parallel branches, however the division is solely based upon the resistances of the parallel paths. Current always tries to flow through the branch having the least resistance. Thus More current will flow in the branch having less resistance and vice-versa. The currents flowing in the parallel branches can be found out by using the current divider rule. Suppose if R1 & R2 are two branches of a parallel connection & i1 & i2 is the current flowing through them respectively. Let 'I' be the original current then the current through R1 can be given as i1=R1/(R1+R2) * I similarly current through R2 can also be calculated.

What is the three laws of parallel circuit?
The potential difference remains the same over the components in parallel and the current splits up proportianally to the components conductances. The components conductances add up to give the combined conductance of the parallel circuit. Conductance is 1 / resistance
What is the total resistance in a parrellel ciruit?
The rule for finding total resistance in a parallel circuit is that a parallel circuit has two or more paths for current to flow through. Another rule states that voltage is the same across each component of the parallel circuit. If one of the parallel paths is broken, current will still continue to flow in all the other paths.
If the resistance in the circuit is increased what will happen to the current and voltage?
* resistance increases voltage. Adding more resistance to a circuit will alter the circuit pathway(s) and that change will force a change in voltage, current or both. Adding resistance will affect circuit voltage and current differently depending on whether that resistance is added in series or parallel. (In the question asked, it was not specified.) For a series circuit with one or more resistors, adding resistance in series will reduce total current and will reduce the voltage drop across each existing resistor. (Less current through a resistor means less voltage drop across it.) Total voltage in the circuit will remain the same. (The rule being that the total applied voltage is said to be dropped or felt across the circuit as a whole.) And the sum of the voltage drops in a series circuit is equal to the applied voltage, of course. If resistance is added in parallel to a circuit with one existing circuit resistor, total current in the circuit will increase, and the voltage across the added resistor will be the same as it for the one existing resistor and will be equal to the applied voltage. (The rule being that if only one resistor is in a circuit, hooking another resistor in parallel will have no effect on the voltage drop across or current flow through that single original resistor.) Hooking another resistor across one resistor in a series circuit that has two or more existing resistors will result in an increase in total current in the circuit, an increase in the voltage drop across the other resistors in the circuit, and a decrease in the voltage drop across the resistor across which the newly added resistor has been connected. The newly added resistor will, of course, have the same voltage drop as the resistor across which it is connected.
How many 15 amps sockets can i connect in a single circuit?
Circuit loading In Canada the code rule is, there shall be not more that 12 outlets on any 2 wire branch circuit. Such outlets shall be considered to be rated at not more that 1 amp per outlet. Where the connected load is known, the number of outlets may exceed 12 providing the load current does not exceed 80 % of the rating of the over current device protecting the circuit.
Suppose that you're facing a straight current-carrying conductor and the current is flowing toward you the lines of magnetic force at any point in the magnetic field will act in?
The lines of magnetic force at any point in the magnetic field of a current flowing towards you will act in the counter clockwise direction. This can be determined by using the right hand rule. Point your thumb in the direction of the current flowing down the straight wire. The curl of your fingers shows the direction of the magnetic lines of flux. The magnetic field of a current is always perpendicular to it. A current facing away from you would produce magnetic lines of force acting in the clockwise direction.
What simple rule has been established for finding the direction of magnetic force around a current-carrying conductor?
The right hand rule. If you were to place your right hand around the conductor, with the thumb pointing in the direction of current flow, your fingers which are wrapped around the conductor will point in the direction of magnetic flux. Said another way, if you are looking at the end of the conductor and current is flowing towards you, then magnetic flux will be counter-clockwise.
How do you round 197.0853 to nearest tenth?
It depends on your rounding rules. The 'averaging rule' is this: 1) If the placement decimal value is 5 or higher, round up. 2) if the placement decimal value is 4 or lower, round down. For this rule, the above number will round to 197.1 If you use the 'truncation rule', you always drop ANY value at that point. For this rule, the above value will round to 197.0

What is the continuous current draw on a 20 amp circuit breaker?
Depends on what you have connected to the circuit. It is less than 10 amps or the breaker would trip. A rule of thumb is you design for about 80% load related to the breaker. For 20 amps that would equal 16 amps.
