If voltage is increased in a circuit what happens to current series and parallel respectively?

In this case current flows from a high voltage to a lower voltage in a 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.


What happens to the applied voltage when a change in circuit resistance occurs?

When a dc supply is connected to a resistor, current flows. The current in amps is equal to the supply voltage divided by the resistance in ohms. The power used is the voltage times the current, and that appears as heat in the resistor, which might become hot to touch.


What is power factor of resistor?

A resistor doesn't have a power factor. However, if a circuit is pure resistance in nature the power factor will be one when a voltage is applied and a current flows in the circuit. The power factor is a measure of the relative phases of the current and voltage in a circuit.


What is short circuit voltage?

Short circuit voltage is the voltage that has to be applied to the primaries of a transformer, so that the nominal current flows through the secondaries, when they are shorted. This value is important, if transformer secondaries shall be used in parallel. Ideally all transformers with parallel secondaries should have the same short circuit voltage. When their short circuit voltages are different, the transformer with the lower short circuit voltage will be loaded more than their relationship of power ratings would predict. The short circuit voltage is also important in the design of a transformer, because it predicts, how much the secondary voltage will drop at nominal output current. This knowledge helps the designer to find out, how many further windings the secondary needs for a certain voltage in relation to an ideal transformer. Short circuit voltage is also known as impedance 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 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.

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 differnece between volts and amperes?

Voltage is power Amperage is current. you can have voltage but nothing runs without a closed circuit and then current flows.


How does a series circuit increase voltage?

In a series circuit, the voltage increases as the electrical current flows through each component in the circuit. This is because the voltage across each component adds up, resulting in a higher total voltage at the end of the circuit.


How does a resistor affect the flow of electricity in a circuit: does a resistor reduce voltage or current?

A resistor affects the flow of electricity in a circuit by reducing the current that flows through it. This reduction in current leads to a decrease in voltage across the resistor.


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).


When does the electric current flow?

What do you need to complete before the current flows?

You need a closed circuit. You also need a voltage source.
