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
How does changing the voltage in a circuit affect the current in the circuit?
Changing the voltage in a circuit will alter the current flowing through it. According to Ohm's Law, the current is directly proportional to the voltage in the circuit. Increasing the voltage will lead to an increase in current, and vice versa.
How does voltage drop work in an electrical circuit?
Voltage drop in an electrical circuit occurs when there is resistance in the circuit, causing a decrease in voltage as the current flows through the components. This drop in voltage is proportional to the amount of resistance in the circuit, following Ohm's Law (V I R).
What does the voltage current graph represent in an electrical circuit?
The voltage-current graph in an electrical circuit represents the relationship between voltage (V) and current (I) flowing through the circuit. It shows how the current changes with respect to the voltage, indicating the behavior and characteristics of the circuit components.
What is the derivative of current with respect to voltage in an electrical circuit?
The derivative of current with respect to voltage in an electrical circuit is called conductance, which represents how easily current flows through the circuit in response to changes in voltage.
Does voltage flow across a circuit or is it impressed across a circuit?
Voltage is impressed across a circuit. Current flows through a circuit.
What is the relationship between voltage potential and electrical current flow in a circuit?
Voltage potential is the force that pushes electrical current through a circuit. The higher the voltage, the greater the potential for current flow. In other words, voltage drives the flow of current in a circuit.
What is the relationship between current and voltage in an electrical circuit?
The relationship between current and voltage in an electrical circuit is described by Ohm's Law, which states that the current flowing through a circuit is directly proportional to the voltage applied across it, and inversely proportional to the resistance of the circuit. In simpler terms, as the voltage increases, the current flowing through the circuit also increases, assuming the resistance remains constant.

How does voltage cause current to work?
Voltage provides the "pressure" to push current "flow" through the circuit resistance.
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)
What does voltage cause?
Voltage causes the flow of electric current in a circuit. It is the driving force that pushes electrons through a conductor, allowing electrical devices to operate. The higher the voltage, the more current will flow through the circuit.
