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.
Normally a high current flows through a short circuit even if there is no change to the voltage. Why is this?
A high current flows through a short circuit even if there is no voltage change because the resistance across the short circuit is zero.
If you double both the voltage and the resistance in a circuit what would be the effect on the current?
If you double the voltage in a circuit, the power is quadrupled, assuming the resistance stays the same.
What measures the volume of electrons through a circuit?
Current measures the flow of electrons through a circuit and voltage basically measure the amount of available electrons.
Current travels from a power plant to a transformer that increases voltage through a what?
circuit
Does voltage flow across a circuit or is it impressed across a circuit?
Voltage is impressed across a circuit. Current flows through a circuit.

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.
What is an equation for power?
Power = (energy used)/(time to use it)Power dissipated by an electrical circuit =(voltage across the circuit) x (current through the circuit)or(resistance of the circuit) x (square of the current through the circuit)or(square of the voltage across the circuit)/(resistance of the circuit)
How does voltage cause current to work?
Voltage provides the "pressure" to push current "flow" through the circuit resistance.
Normally a high current flows through a short circuit even if there is no change to the voltage. Why is this?
A high current flows through a short circuit even if there is no voltage change because the resistance across the short circuit is zero.
What is the relationship among voltage circuit and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
what is current controller voltage source?
A voltage source whose voltage varies proportionally to a current flowing through some other path in the circuit.
If you double both the voltage and the resistance in a circuit what would be the effect on the current?
If you double the voltage in a circuit, the power is quadrupled, assuming the resistance stays the same.
What force keep current flowing?
Voltage is the pressure that moves the electrons (current) through a circuit.
What measures the volume of electrons through a circuit?
Current measures the flow of electrons through a circuit and voltage basically measure the amount of available electrons.
Does the voltage increase when current moves through the circuit?
If a buck boost converter is a part of the circuit, then it is possible.
In a series circuit what happens to the current if you increase the number of components in the circuit?
The current (amps) will remain constant, but the voltage will drop.
