What is the logic behind flow of electricity without circuit?
current
If voltage changes in a ac circuit what happens to current?
Voltage attempts to make a current flow, and current will flow if the circuit is complete. It is possible to have voltage without current, but current cannot flow without voltage. The answer is "yes",voltage remains the same as current moves through the circuit.As the voltage remains constant, current increases in the circuit.
Does the current generates if there is no resistance in the circuit?
You can have current without resistance. You would just have zero voltage drop across that zero resistance.However, the question is very interesting, because if you really had zero resistance in the entire circuit, it would be impossible to have any voltage at all without generating an infinite current, so the answer in the theoretical case is no, you can have no current, nor voltage, if there is no resistance at any point in the circuit.
What is the relative resistance of a good ammeter and a good voltmeter?
A good ammeter has low resistance to ensure it does not significantly affect the current flowing through the circuit it is measuring. In contrast, a good voltmeter has high resistance to minimize the current drawn from the circuit, allowing it to measure the voltage across a component without altering its behavior. This difference in resistance characteristics is crucial for accurate measurements in electrical circuits.
What is the difference between reverse current and overcurrent protection?
A reverse current relay senses Power in (uses both voltage and current, and looks at the phase angle between these), and operates if power is flowing in the reverse direction, and the current is above a set point. An overcurrent relay looks at only current, and operates if it is above a set point regardless of power flow direction. Reverse current relays are often referred to as reverse power relays.
How do you measure dc current in an electric current?
measuring current usually requires opening the circuit to allow a meter to be inserted in series with the circuit, although clip-on current probes are available (but are rather expensive and typically bulky) that can simply be clipped around a wire without needing to modify anything.
What is the term for measuring pressure without taking into account the current atmospheric pressure?
The term for measuring pressure without considering the current atmospheric pressure is called gauge pressure.
What is the purpose of an insulator?
Keeps the current in the conductor. Without the insulation on a conductor the current can and will leave the intended path in the electrical circuit if it comes in contact with some other conductive path if there is a difference of potential.

Can you have current without voltage in a circuit?
YEs if Merlin is at the one end of the line and harry potter at the other, then it is possible.

Even without current flow there can be voltage in a circuit?
Voltage is potential energy and can exist in a open circuit.
What constitutes a complete circuit?
Where the current can flow around completely, without being interrupted by a break in the circuit.
Will a circuit work without a switch?
Yes, a circuit can work without a switch if it is designed to be always on or if the components are connected directly without the need for a switch to control the flow of current. However, in many applications, a switch is necessary to control when the circuit is on or off.
The power in an electrical circuit is given by the equation P I2R where I is the current flowing through the circuit and R is the resistance of the circuit. What is the power in a circuit that has a c?
The power in a circuit is determined by multiplying the square of the current flowing through the circuit by the resistance of the circuit. Without specific values for current and resistance provided, the precise power cannot be calculated.
Where are circuits?
Circuits are used anywhere you want to have an electrical current flow. Without a circuit, you cannot have current flow. Without current flow, you cannot do any work.
What would happen to circuit if there was no resistance?
a circuit with no resistance or zero resistance can be considered as open circuit in which the current is zero. without resistance the circuit just becomes open ()
