Voltage is the force that causes current to flow through a circuit. In a similar way it isn't pressure that flows through a pipe - it is the fluid flowing through a pipe due to a difference in pressure at the entry and exit of the pipe that causes the fluid to flow through, no pressure flowing through a pipe.
What else can I help you with?
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 voltage source and what is the conductor in a circuit?
The voltage source is the source of the electricity. The conductor is what the electricity flows through to reach its destination. Example: A battery is a voltage source and an electrical wire is the conductor.
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.
What limits the current that flows through a circuit for a particular appllied DC voltage?
The voltage applied and the resistance across it.
Why potential difference across open circuit is more than in closed circuit?
In a closed circuit there is a potential drop due to resistance of wires and battery (internal).AnswerWhen the circuit is closed, the resulting current not only flows through the external circuit, but through the source (battery, generator, transformer, etc.) itself. All sources have an internal resistance, which causes an internal voltage drop, slightly reducing the voltage across the terminals. The larger the current, the larger the internal voltage drop, and the lower the terminal voltage.When the circuit is open, no current flows. So there is no internal voltage drop, and the full voltage appears across the source's terminals.The 'open-circuit voltage' is actually the electromotive force provided by the source.
Does voltage flow across a circuit or is it impressed across a circuit?
Voltage is impressed across a circuit. Current flows through 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 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.
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 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 a fuse or circuit breaker do when too much electricity flows through a circuit?
A fuse or circuit breakers purpose in a circuit is to disconnect the circuit load from the voltage source when a circuit fault occurs.
What flows through a complete circuit?
Current flows through a complete circuit.
What is the voltage source and what is the conductor in a circuit?
The voltage source is the source of the electricity. The conductor is what the electricity flows through to reach its destination. Example: A battery is a voltage source and an electrical wire is the conductor.
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.
How does a electrical current flows through a circuit?
If a voltage is applied, electrons (or other charge carriers) are subjected to an attraction towards one side, and a repulsion from the opposite side. This results in the current, i.e., the flow of charge carriers.
What causes voltage drop in electrical circuits?
Voltage drop in electrical circuits is caused by the resistance in the wires and components of the circuit. When current flows through a circuit, some of the electrical energy is converted into heat due to this resistance, leading to a decrease in voltage along the circuit.
What are the 2 kind of circuit?
The two basic circuit types are series circuits and parallel circuits. In a series circuit, all the current flows through each component, and each one drops some of the applied voltage. In a parallel circuit, the applied voltage is dropped across each parallel component and current "splits" so some flows through each component.
