no we not use resistance in place of diode.


Use Ohm's Law and explain how 2 circuits have the same current but different resistance?

As we know V=IR, by changing the voltages in the two different circuits, we can maintain the same current even we have different resistance.


What two circuits one series and one parallel use light bulbs to provide resistance. Both circuits have the same number of light bulbs?

What is the relationship between resistance and temperature in electrical circuits?

In electrical circuits, the resistance of a material typically increases as its temperature rises. This relationship is known as temperature coefficient of resistance.


What does starting resistance refer to in the context of electrical circuits?

Starting resistance in electrical circuits refers to the initial resistance encountered by a device when it is first turned on. This resistance can affect the flow of current and the performance of the device.


How can you solve resistance to complicated circuits like diamond shaped circuits?

One way is to use Thevenin's theory and methods. Léon Charles Thévenin was a French telegraph engineer who extended Ohm's Law to the analysis of complex electrical circuits.


What are the multiple resistance circuits?

Multiple resistance circuits are electrical circuits that contain more than one resistor connected in various configurations, such as series, parallel, or a combination of both. These circuits are commonly used in electronic devices and systems to control the flow of current and voltage. The total resistance in a multiple resistance circuit can be calculated using different formulas depending on the arrangement of the resistors.


Why dont series circuits shine as bright as parallel circuits?

By connecting components in series, you are increasing the equivalent resistance (known as thevenin resistance) of the circuit. Power is equivalent to Voltage^2 / Resistance. Therefore, by increase the resistance, you are decreasing the amount of power provided by the source.


What is the relationship between resistance and the symbol omega in electrical circuits?

In electrical circuits, resistance is represented by the symbol omega (). Resistance is a measure of how much a material or component opposes the flow of electric current. The symbol omega is used to denote resistance in equations and circuit diagrams.


Which of the statements concerning parallel circuits is NOT true?

D. The total resistance is equal to the lowest resistance in the circuit


Why in DC it is called as Resistance and impedance in AC Circuits?

Resistance applies to both d.c. and a.c. circuits, and is determined by the resistivity, length, and cross-sectional area of a conductor.In d.c. circuits, resistance is the only opposition to the passage of current. However, in a.c. circuits, the flow of current is opposed, not only by resistance, but also by reactance. Reactance is caused by a circuit's inductance or capacitance, or both, and varies with the frequency of the supply. Like resistance, reactance is also measured in ohms.So, in a.c. circuits, the combination of resistance and reactance is called 'impedance'.Impedance is not the algebraic sum of resistance and reactance, but the vectorial sum. So if, for example, an a.c. circuit had a resistance of 3 ohms and a reactance of 4 ohms, the impedance would be 5 ohms, not 7 ohms.


What causes resistance in electrical circuits?

Resistance in electrical circuits is caused by the interaction of electrons with the atoms in a material, which slows down the flow of electric current. This resistance is measured in ohms and can be influenced by factors such as the material of the conductor, its length, and its cross-sectional area.
