Does sugar create electrical resistance?
Sugar is not used in electrical circuits.
When you have multiple circuits connected to a site the entire circuit is known as a what?
virtual circuit
An opposition to current flow that occurs in alternating current circuits is called?
Capacitive reactance.
Why do solar cells need to lower resistance in the electrical circuits that make up their electronic system?
Reducing the resistance of solar cells increases the output current. Although the voltage remains the same the current is effected due to internal resistance. A reduction in output current can result in lesser diminished functioning in household appliances.
Why doesn't the wire get hot in a circuit going from a battery through a light bulb?
Actually the wire WILL get hot, but specifically HOW MUCH it gets hot depends on the current, and on the resistance of the wire.In most circuits, the resistance of the wire (and thus, the amount of heating) is insignificant, and can safely be ignored for most calculations.
Are parallel circuits like series circuits?
They are not exactly the same. A series circuit is one complete circuit with not other pathways. A parallel circuit is a complete circuit with multiple pathways . The resistance of a parallel circuit is completely different from the resistance of a series circuit. Therefore, this affects the voltage and the current produced,
Can you use resistance in place of diode in clipping circuits?
no we not use resistance in place of diode.
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.
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.
Does sugar create electrical resistance?
Sugar is not used in electrical circuits.
What is the opposition of current flow measured in?
The opposition of current flow is measured in ohms. For DC circuits it is resistance and for AC circuits it is impedance.
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 is advantage of a parallel circuit?
Parallel circuits have a higher current and a lower resistance.
In the simplest of dc circuits where the resistance is zero what kind of circuit is it?
A short circuit.
How do you calculate equivalent resistance in complex circuits mathematically?
Using superposition theorem.
What two circuits one series and one parallel use light bulbs to provide resistance. Both circuits have the same number of light bulbs?
Series circuit gives higher resistance compared to parallel circuit.
