The total current that flows through a circuit is the same as the current that flows through each individual parallel sub-circuit.?
True...!
Describe how a battery can create a current in a conducting wire?
The battery produces a voltage; if a conducting wire - or any circuit for that matter - is connected, a current will flow according to Ohm's Law, that is, the current is calculated as voltage / resistance.
How do you calculate current in units?
The unit for current is ampere. Calculations include Ohm's Law (V=IR), and Kirchhoff's Current Law.
What does kirchoff's law state?
Kirchhoffs Laws are statements about circuits. There are two laws ; 1) The total current entering any point in a closed circuit equals the total current leaving that point. 2) The sum of the voltage changes around any closed path is zero. These "Laws" are a consequence of the more fundamental laws of conservation of charge and conservation of energy.
What is the relationship between the voltage and the current when the resistance is kept constant?
Ohm's Law: voltage = current * resistance. If resistance is a constant, then voltage is directly proportional to current.
What does kirchhoffs current law say about the current entering the point in a circuit?
Total current entering a node is always zero.
When using kirchhoffs current law if negative answer is found for current flow what does this indicate?
It means the current is moving in the opposite direction to the one you assumed.
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.
The total current that flows through a circuit is the same as the current that flows through each individual parallel sub-circuit.?
True...!
Is ohm's law in Vrms or Vpp?
It doesn't matter as long as you measure both voltage and current in same units.

Why does ohm's matter with speakers?
the vibration produced in the coil of a speaker is due to current passing through it hence it obey ohms law
Where is the best place to put an ammeter in the circuit to measure the current going through the light bulb?
Since (by Kirchoff's current law) the current in a series circuit is the same at every point in the series circuit, it does not matter where you place the ammeter.
What matter is current?
flow of charge is current
What law states that matter can never created or destroyed?
The law of conservation of matter
The law of conservation of what?
If by the law of conservation you mean the Law of Conservation of Matter, then it states that matter cant be created or destroyed.
How does law of conversion of matter relate to Environmental science?
The law of conservation of matter is the law that says that matter cannot be created or destroyed, but can only change form
