voltage does not flow, current flows
Answer'Voltage' is another word for 'potential difference' -you can think of it as being the equivalent of the difference in pressure across, say, the input and output ports of a central heating radiator which is responsible for pushing water to flow through that radiator. So 'voltage' exists across two points in a circuit, causing current to flow through the conductor between those two points.
What else can I help you with?
What is voltage drop in an electrical circuit?
When a current flow on a conductor , or load or resistor, some voltage will drop across that load or resistor.AnswerA voltage drop is the potential difference appearing across individual components in a circuit, necessary to drive current through those components. The sum of the individual voltage drops around a series circuit will equal the supply voltage applied to that circuit.
Why does higher resistance have a larger voltage drop across it?
In a d.c. circuit, voltage drop is the product of resistance and current through that resistance.
Give the characteristics of a parallel circuit?
-- The voltage across every circuit element is the same, and is equal to the power supply voltage. -- The current through each circuit element is in inverse proportion to its impedance. -- The sum of the currents through all circuit elements is equal to the power supply current.
In which circuit is the voltage the same across all branches?
Parallel circuit.
How does voltage change across an appliance in a parallel circuit?
With the minor voltage loss in the wiring, the voltage drop across a single appliance is the total voltage in the circuit, and doesn't change when more devices are added in parallel.
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 voltage drop running through the parallel potion of the circuit?
A: There is no voltage drop running through in a parallel circuit but rather the voltage drop across each branch of a parallel circuit is the same
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 is the potential voltage across the circuit components in a series circuit?
In a series circuit, the potential voltage across the circuit components adds up to the total voltage of the circuit.
What is the rule for voltage across each resistor?
The rule for voltage across each resistor in a series circuit is that the total voltage supplied by the source is equal to the sum of the voltage drops across each resistor. In a parallel circuit, the voltage across each resistor is the same and equal to the source 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.
The voltage measured directly across an open switch in a circuit will be?
The voltage measured across an open in a series circuit is the equivalent of the sourse voltage.
How is a parallel circuit the same as a series circuit?
In both cases, the power dissipated is measured by multiplying the voltage across the circuit by the current through the circuit.
Is a series circuit the same as a parallel circuit?
In both cases, the power dissipated is measured by multiplying the voltage across the circuit by the current through 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.
Why the voltage in parallel circuit is the same across each circuit?
In a parallel circuit, each component has its own separate pathway for current flow. Therefore, the voltage across each component remains the same because the voltage source pushes the same amount of voltage through each pathway simultaneously.
What is voltage drop in an electrical circuit?
When a current flow on a conductor , or load or resistor, some voltage will drop across that load or resistor.AnswerA voltage drop is the potential difference appearing across individual components in a circuit, necessary to drive current through those components. The sum of the individual voltage drops around a series circuit will equal the supply voltage applied to that circuit.
