What law is used to find the polarity of resistor when two voltage source are connected?
Hi! Well, it depends what voltage is "pushing" harder on the resistor. If you are ONLY dealing with 2 voltage sources and a single resistor, then the voltage source with the higher potential (or voltage) will dictate what polarity the resistor is. Cheers!
What is the purpose of fixed resistor?
To lower the voltage and amperage in order to better fit the needs of other components.
If you have a voltage source of 120 volts with a 840 ohm resistor 2000 ohm resistor and a 560 ohm resistor?
I don't see a question. Please clarify if you want an answer.
What is the resistor of 18 ohms when connected to a 9v battery?
Even though it is connected to a 9 volt source, it is still a resistor.
What is the voltage across the first ohm resistor?
if R4 is the only resistor (the load), then the drop would be the same as the energy source
Can a transistor can act like resistor capacitor inductor?
A transistor acts like a resistor when Gate is connected to Source.
Describe the purpose of the coloured bands on a resistor?
The purpose of colored bands on a resistor is to tell whoever is installing the resistor the amount of resistance that particuliar resistor has.
What are the basics of how flashlights work?
You need a conductor, power source and a resistor. You need a conductor, power source and a resistor. You need a conductor, power source and a resistor.
How you make NOT gate by using X-OR gate?
Tie unused input high through pullup resistor.
How do you install a resistor in an DC circuit?
It depends on the purpose for installing the resistor. If the intent is to decrease current flow, the resistor must be connected in series with the load. If the purpose is to increase current flow, the resistor must be connected in parallel with the load. To connect a resistor in series, connect the resistor to one side of the power source, in line with the load. This will decrease circuit current flow. To connect a resistor in parallel, connect the resistor between the positive and negative sides of the power source, which will effectively connect the resistor across the load . This will increase current flow through the circuit. However, before connecting a component in parallel, make sure the increase in current flow will not exceed the current rating of the circuit or fuses/breakers will blow.
What is general purpose resistor?
General purpose resistor is used to resist the current flow.the common resister is general purpose resister.
What is the purpose of a resistor connected in the series with the load resistor?
Divide the voltage
Why you need to connect resistor in series for the practical voltage source?
A resistor is connected in series with a practical voltage source in order to determine the current produced by the source.

How does a pull down resistor work?
Typically used in logic circuits is the pull-up resistor Less common is the pull-down resistor It's purpose is to force a zero (low) value when no other component is driving the input (no load) By providing a current limited path to negative power source through the resistor, while allowing the voltage to swing high if a load is present.
How does a resistor TBA820 work?
The TBA820 is a 2 watt general purpose amplifier integrated circuit, not a resistor.
