What else can I help you with?
What would happen if they was no resistance?
current would go to a maximum, (if there was voltage present), if there was no voltage, no current would flow. the only thing that would limit the current flow (if voltage is present) is the small resistance of the cables, but say there was no resistance it would be like in a short circuit maximum current would flow at the instant voltage is applied. that is why RCD's work as they should, you want the most amount of current to flow at once because otherwise if the current was limited it would not trip in time to stop someone getting electrocuted.
How does a resistor work to limit the flow of electric current in a circuit?
A resistor limits the flow of electric current in a circuit by providing resistance to the flow of electrons. This resistance reduces the amount of current that can pass through the circuit, helping to control the flow of electricity and prevent damage to components.
How does voltage cause current to work?
Voltage provides the "pressure" to push current "flow" through the circuit resistance.
Which diode will work when two different diodes are in parallel?
the path of least Resistance electricity is like water it flows in the direction of least Resistance so current should flow in the diode with the lowest Resistance but if the draw on current was high enough it would also start to flow in the higher resistance diode
In electrical work resistance is often represented by the?
In electrical work, resistance is often represented by the symbol "R" and is measured in ohms (Ω). It describes how much a material or component impedes the flow of electric current. The higher the resistance, the more difficult it is for current to flow through a circuit.
Why must you make current flow through the meter in order to measure it?
You don't. ...unless you want to directly measure the current in a circuit branch. That's the purpose of an ammeter. You can also use a volt meter if you know the resistance of a resistor in that branch to determine current (assuming DC circuit here) - current = voltage / resistance. This may be more useful for circuitry that is on a breadboard, since inserting an ammeter may not be practical.
How do resistors work in an electrical circuit?
Resistors work in an electrical circuit by limiting the flow of electric current. They are designed to resist the flow of electricity, which helps control the amount of current passing through a circuit. This resistance is measured in ohms and can be adjusted by changing the value of the resistor.
How does electricity work and what are its fundamental principles?
Electricity is the flow of electric charge through a conductor, such as a wire. It is generated by the movement of electrons in atoms. The fundamental principles of electricity include voltage, current, and resistance. Voltage is the force that pushes the electric charge, current is the flow of electric charge, and resistance is the opposition to the flow of electric charge. These principles are described by Ohm's Law, which states that the current flowing through a conductor is directly proportional to the voltage applied and inversely proportional to the resistance of the conductor.
Will a circuit work without a switch?
Yes, a circuit can work without a switch if it is designed to be always on or if the components are connected directly without the need for a switch to control the flow of current. However, in many applications, a switch is necessary to control when the circuit is on or off.
How does an electrical insulator work?
Electrical insulators work by preventing the flow of electric current through them. They are materials with high resistance to the flow of electricity, which keeps the current from passing through them to avoid short circuits or electrical shocks. Insulators can be found in materials such as rubber, glass, and plastic.
What happens to a fuse when the flow of charges stop?
Current i.e.rate of flow of charge when stops flowing in a circuit then fuse does not blows out. The only work of fuse is to blow away when the current starts flowing greater in magnitude than the rated current value.
Will current flow in a higher resistance or in lower resistance if they are connected in parallel to a voltage source?
Current will always flow in both resistors, but the one with the lower resistance will have more current flow through it. The value of the current in each resistor is calculated by dividing the voltage of the source by the resistance of the individual resistor. As long as the capability of the power source isn't exceeded, the current through each resistor isn't affected by the presence of the other resistor. Said another way, if two resistors are connected in parallel across a source, neither one "cares" that the other resistor is connected across the source. The two resistors work independently.
