Explain how the amount of current that flows out of the battery is related to the amount of current in the branches of the circuit?
Kirchoff's Current Law: The signed sum of the currents entering a node is equal to zero. This means that the current leaving the battery is equal to the sum of the currents in the branches of the circuit.
Should all three phases of 3 phase motor are to be equal on no-load and load conditions?
Ideally all three phase currents will be equal. There may exist some voltage imbalance from the power source, which will result in unequal currents.
The sum of currents across the resistors equals the currents through the source in which type of circuit?
In parallel circuit the current through the resistors are different in values depending upon the values of resistors. But the sum of the currents across all the resistors will be equal to the current through the sourcgsvg bdjasuhafyuhda
How a transistor transfers resistance?
The input current of transistor is approximately equal to output current .Suppose in common base configuration the emmiter current is approximately equal to collector current if neglect the very small value of bae current.Even though the input resistance is not equal to output resistance,the currents are same ,so we can reliase that the transistor transfers resistance to get same currents at both ends.
Is the neutral conductor of a two wire single phase circuit considered a current carrying conductor?
Sure. In a two-wire circuit, both wires carry equal currents.
Kirchoff's law that states the sum of the currents entering the node is equal to the sum of the currents leaving the node on a parallel circuit?
KCL (Kirchoff's Current Law) applies to any circuit, not just parallel circuits. The sum of the currents entering a node will always equal the sum of the currents leaving the node. KVL states that the sum of the voltages around a closed loop is always zero.
Explain how the amount of current that flows out of the battery is related to the amount of current in the branches of the circuit?
Kirchoff's Current Law: The signed sum of the currents entering a node is equal to zero. This means that the current leaving the battery is equal to the sum of the currents in the branches of the circuit.
How the amount of current that flows out of the battery is related to the amount of current in the branches of the circuit?
Kirchoff's Current Law: The signed sum of the currents entering a node is zero. Assume the top of the battery is a node. The current entering it (from the battery) is equal to the sum of the currents leaving it (to the branches). This adds up to zero.
Is the current in one branch of a parallel circuit more than less than or equal to the total current entering the junction point of the circuit?
Answer: less. Answer: Kirchhoff's Current Law states that the sum of all currents into a junction (or out of a junction) must be zero. This refers to the algebraic some, that is, if you consider the current into the junction, any current entering the junction will be counted as positive, while any current leaving the junction will be counted as negative. Thus, any individual current will be equal to the negative of the sum of all the other branches at the junction.
Does the algebraic sum of the currents due to individual source equal the total currents due to the two sources?
Yes, it does. It must, because current is composed of physical electrons, which aren't created or destroyed, so the count of electrons entering and leaving each source, and flowing through the circuit, must all tally up.
Is any current lost as it moves around a circuit?
No. Kirchoff's Current Law states that the signed sum of the currents entering a node is equal to zero. A consequence of this is that, for series circuits, the current is the same at every point in the circuit.
What is the resultant current in parallel circuit combining of 2 or more currents that are in phase?
The phasor sum (kind of like a vector sum) of the legcurrents in a parallel network will equal the current entering the network. If all currents are in phase, then just add up the magnitudes of the currents.
Is current the same at all points in a circuit?
By Kirchoff's current law, the sum of the signed currents entering a node is zero. In a parallel circuit, this means the sum of the (often single) current(s) entering a node (junction) is the same as the sum of the (two or more) currents leaving that node. To determine the current in a particular branch, you need the voltage and resistance, or you need something else that you can use to calculate the current. In the second case, if you know the total current and one branch current in a two branch circuit, you know the other branch by calculating total minus first branch. For the first case, one method is to take advantage of Kirchoff's voltage law, which states that the signed sums of the voltage drops around a series circuit is zero. In a parallel circuit, this means that the voltage drop across each branch is the same. If you then also know resistance, you know current.
What is the strength of current in each resistor of a series circuit?
The current in each resistor in a series circuit is the same. Kirchoff's Current Law states that the sum of the currents entering a node must add up to zero. The connection between two resistors in a series circuit is a node. The current entering the node from one resistor is equal to the current leaving the node into the next resistor.
Which of kichhoff's laws applies to series circuits?
Kirchoff's Current Law states that the signed sum of the currents entering a node is equal to zero. In a simple parallel circuit, say with one battery and two light bulbs, this means the current coming out of the battery will be exactly equal to the sum of the currents entering the two light bulbs. In a series circuit, it also means that the current at every point in the circuit is the same. A parallel circuit can be construed as a special case of a series circuit, when you start to combine elements. Kirchoff's Voltage Law states that the signed sum of the voltage drops around a series circuit is equal to zero. Since a parallel circuit can be construed as a special case of a series circuit, this means that voltage across parallel nodes is equal.
What is the formula for Kirchoff's current for parallel circuits?
Kirchoffs's current law states that the sum of all the currents flowing out of any point is equal to zero. In other words, the current flowing in is equal to the current flowing out.In the case of a parallel circuit, this means that if a single current branches into two or more parallel branches, then the sum of the currents in the parallel branches must be equal to the original current before it branched.
How do angles of light entering and leaving a mirror compare?
The angle formed from the ray approaching the mirror and the normal (imaginary line that's perpendicular to the mirror) is equal to the angle formed by the reflected ray and the normal. See link below for "Image"... In this image, angle I and angle R are equal
