What condition are necessary for a current to be present in a circuit?

The only two things needed for current flow are electromotive force or voltage and a conductor. The amount of current flow will depend on the "Resistance" in the circuit.

What conditions are necessary for a current to be present in a circuit?
some resistance and potential difference
The amount of current in a circuit can what by increasing the amount of resistance present in the circuit?
No it cant. Voltage = Current x Resistance. So at constant Voltage if the Resistance is increased, Current will reduce
How has the past influenced us today?
The past has influenced us today by shaping our traditions, cultures, and societal norms. Historical events and experiences have played a significant role in shaping our identities, beliefs, and values, ultimately influencing how we interact and perceive the world. Understanding the past allows us to learn from our mistakes, appreciate our accomplishments, and make informed decisions for the future.
What measures the flowing in a circuit?
The flow in a circuit is called the electric current and it is measured by voltages. The number of volts that are present in the charge will determine the strength of the electric current.
Which tense indicates an action or condition in the current time?
The present tense.
What happens to current in a parallel circuit?
in a parallel circuit, current get divided among the parallel branches in a manner so that the product of current and the resistance of each branch becomes same. The sum of the current in each branch is equal to the total current of the circuit.
What is the definition of Necessary and sufficient causes?
A necessary cause is a condition that, by and large, must be present for the effect to follow. A sufficient cause, in contrast, is a condition that more or less guarantees the effect in question.
If are measuring current in a series circuit with a multimeter and get a reading of 0.01 mA what does it mean?
0.01 mA is 0.00001 A. This is the current required to develop a voltage of 0.01 mV across 1 Ohm. Since it is a series circuit, it is also true that the current on 0.01 mA is present at every point in the circuit.
What are the conditions necessary for rusting?
The conditions necessary for rusting are water (or water vapour) and air, specifically Oxygen. If one condition is absent and the other is present then rusting would not occur but if both are present then rusting will occur
Should a 24vdc circuit create arcing to use as a switch or signal?
Some voltage must be present but the current causes the arcing.
Why fuse not used in the neutral?
The fuse (or circuit breaker) must open the hot line to prevent an unsafe condition resulting from voltage still being present in the circuit. The hot line could short to something and still cause a fire or it could electrocute a person. Just breaking the current loop via the neutral is not enough for safety!
Why must there be no gaps in an electric circuit for it to carry current?
Current travels through free electrons (These are present in most transitional metals and some allotropes of carbon (I.E. Graphite)), when there is a break in a circuit (No metal present) the current cannot travel the gap, unless it is of sufficient energy to "arc" through the air to connect the gap. However this will only occur if completing the circuit is the easiest and quickest way to ground itself (Hence why people get electric shocks, we, being made up of mostly water, conduct electricity better than air, so the current passes though us to ground).
