What is a rule for current flowing round a circuit?
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.
What is the current of a series-parallel circuit connection?
The current flowing through a series circuit is (voltage between the circuit's ends) / (sum of all resistances in the circuit). The current is the same at every point in the series circuit.
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.
What is the formula for total current in a series circuit?
Current = (Voltage across the circuit) divided by (Total resistance of the circuit). The current is the same at every point in the series circuit.
Why does not it matter where you measure the current in a simple circuit?
The current measured at any point in a simple circuit will be the same because current is the measure of electron flow through a circuit. The current flowing through any branch of any circuit (or an entire simple circuit) will always be the same at any point.
What do you find out about the current at different places in the series circuit?
The current at different places in a series circuit is the same. Kirchoff's current law states that the signed sum of the currents entering a node is zero. A consequence of this is that the current at every point in a series circuit is the same.
Why Kirchhoffs current law and Kirchhoffs voltage law cannot apply on distributed circuits?
Actually, they do apply.Kirchoff's Current Law states that the signed sum of the currents entering a node is zero. This applies whether the node has only two connections, such as in a series cicuit, or more than two connections, such as in a parallel circuit. Some people confuse this with the rule that current at every point in a series circuit is the same. That is just a special case of KCL, but the real rule has to do with the node, and not the circuit.Kirchoff's Voltage Law states that the signed sum of the voltage drops going around a series circuit is zero. This applies for simple series circuits as well as for complex series/parallel circuits. Pick any loop in a circuit and walk around it - you will find that the signed sum of the voltage drops is zero, no matter what.

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 current of a series-parallel circuit connection?
The current flowing through a series circuit is (voltage between the circuit's ends) / (sum of all resistances in the circuit). The current is the same at every point in the series circuit.
Does current get lost in a circuit?
No. Current does not get lost in a circuit. By Kirchoff's Current Law, the signed sum of currents entering a node is zero, which means that the current at every point in a series circuit is the same. Power may get lost, by conversion to heat, but do not confuse power, voltage, and current - they are three different things.
The total current that flows through a circuit is the same as the current that flows through each individual parallel sub-circuit.?
True...!
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.
Is it possible to use a switch to turn off only one bulb in a series circuit?
No. In a series circuit, current is the same, by Kirchoff's current law, at every point in the circuit, so you either have current at every point, or you have no current at every point.
What is the formula for total current in a series circuit?
Current = (Voltage across the circuit) divided by (Total resistance of the circuit). The current is the same at every point in the series circuit.
In a series circuit the is the same at every point?
In a series circuit, components (such as resistors, bulbs, or other devices) are connected end-to-end so that there is only one path for the current to flow. Because there is only one pathway for the current, the same current passes through each component in the circuit. This principle is derived from the conservation of electric charge. Since charge cannot accumulate or disappear in a closed circuit, the current that enters a component must be equal to the current that exits that component. In other words, the flow of current is continuous and consistent throughout the series circuit. Mathematically, this can be expressed as: I_total = I_1 = I_2 = I_3 = ... = I_n Where: I_total is the total current entering the series circuit. I_1, I_2, I_3, ..., I_n are the currents through each individual component in the circuit. It's important to note that while the current remains the same throughout a series circuit, the voltage (potential difference) across each component can vary depending on its resistance or impedance, according to Ohm's Law (V = I * R).
Why does not it matter where you measure the current in a simple circuit?
The current measured at any point in a simple circuit will be the same because current is the measure of electron flow through a circuit. The current flowing through any branch of any circuit (or an entire simple circuit) will always be the same at any point.
