- Why in a circuit, when a resistor is connected parallel to a voltage source, or in series with current source, we can get rid of that resistor ?
.
A resistor is an electrical component that is used to limit the flow of electric current in a circuit. It works by converting electrical energy into heat, thus reducing the amount of current that can pass through it.
When a resistor is connected parallel to a voltage source, it means that both the resistor and the voltage source are connected to the same two points in the circuit. This results in the voltage across the resistor being the same as the voltage across the voltage source.
Connecting a resistor parallel to a voltage source decreases the overall resistance of the circuit. This is because the current has more than one path to flow through, resulting in a lower total resistance.
Yes, connecting a resistor parallel to a voltage source can affect the voltage across other components in the circuit. This is because the voltage across the resistor is the same as the voltage across the voltage source, and this voltage is shared among all components connected in parallel.
One practical application of connecting a resistor parallel to a voltage source is in voltage regulation. By adjusting the value of the resistor, the voltage across the voltage source can be regulated. This is commonly used in electronic devices to ensure a consistent and safe voltage supply.
