How kirchoff's current law is satisfied in a three phase unblanced star connected load supplied from three phase three wire supply?
Kirchhoff's (not 'Kirchoff's') Current Law specifies that 'the sum of the currents at any junction is zero'. For a d.c. circuit, this refers the the algebraic sum but, for a.c. circuits, this refers to the phasor (vector) sum.So, Kirchhoff's Current Law is satisfied because the phasor-sum of the three phase currents (balanced or unbalanced) at the star point is equal to zero. You have to understand that the three phase currents are displaced from each other, so that they are not all travelling towards the star point at the same instant.
Can a water softener and a chest freezer be on the same circuit?
Yes but the circuit must be capable of supplying the sum of the currents needed for the two appliances.
Is KVL and KCL applicable to a c circuit?
Yes, Kirchhoff's Voltage Law (KVL) and Kirchhoff's Current Law (KCL) are applicable to all types of circuits, including DC circuits. KVL states that the algebraic sum of voltages around any closed loop in a circuit is zero, while KCL states that the algebraic sum of currents entering a node is equal to the sum of currents leaving the node in a circuit.
What is the ability to transmit electrical currents called?
The ability to transmit electrical currents is called conductivity. Materials that conduct electricity well are known as conductors, while those that do not conduct electricity are known as insulators.
Does liquid in the inner core flow in currents?
Yes, the liquid outer core of the Earth experiences convective currents due to variations in temperature and composition. These currents are responsible for generating the planet's magnetic field through a process known as the geodynamo.
Is the sum of the separate currents equal to the total current?
Yes, in a closed circuit, the sum of the currents flowing into a junction is equal to the sum of the currents flowing out of the junction. This is known as Kirchhoff's current law.
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.
What law states that the sum of all currents entering a node must equal the sum of all currents leaving that node?
Kirchhoff's Current Law
How does maxwell's mesh equations differ from Nodal equations?
Maxwell mesh equations otherwise known to most engineers as "loop analysis" is taking the sum of the voltages around closed loops in the circuit and setting them to zero (conservation of energy), then solving for the currents. Nodal equations otherwise known as "nodal analysis" is taking the sum of the currents entering and/or leaving the circuit at any particular node and setting them to zero, then solving for the currents.
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.
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
Under what conditions is the sum of the currents zero in star connected load?
yes
How is a total current in a parallel circuit worked out?
sum the individual branch currents
What is the formula for bjt power consumption?
it is the collector voltage multiplied by the sum of all the currents.
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.
What happens if current flows through 2 parallel current in the same direction?
With the possible exception of some circuits that have inductance and capacitance in parallel and are excited by a pulse or an alternating voltage, the currents in two parallel branches of a circuit are ALWAYS in the same direction.
What may be the maximum neutral current in unbalanced nonlinear load?
The sum of all phase conductor currents.
