How does resisitance affect currents?
The higher the resistance the less current can pass through therefore the current will be lower.
What will happen in a series circuit if one bulb is added?
If one more light bulb is added to a series string of light bulbs while the voltage supplied across theends of the string remains constant, then the total resistance of the string increases, causing thecurrent in the string to decrease, and every bulb glows less brightly than it did before the new onewas added.
Why does resistance increase in thinner wires?
A thick wire has its cross section area more than that of the thin one .Since the resistance of a material is inversely proportional to its resistance, resistance of thick wire is less compared to.[as cross section area increases the no electrons drifted increases].this applies only to OHMICdevices.
Why is resistance less when resistors are join in parallel?
What do you mean? In a parallel circuit, the combined (or effective) resistance is less than any individual resistance.
What happens to the brightness of the bulbs in a parallel circuit?
A lamp's rated power only applies when the lamp is supplied with its rated voltage. If you connect the lamps in series, with the same supply voltage, then the lamps are no longer subjected to their rated voltage and, so, will not operate at their rated power.
Why do bulbs get dimmer in series circuits?
When light bulbs are connected in series circuits, they will get dimmer whenever a bulb is added. This is because the current is shared between all of the bulbs equally.AnswerLamps only operate at their rated power when subjected to their rated voltage. If you connect lamps in series, each lamp will be subject to a lower voltage, so they will not operate at their rated power and, so, will be dimmer. The more powerful lamps will actually glow less than the less-powerful lamps because their resistance is lower and the voltage drop across them will also be lower than the voltage drop across the less powerful lamps.
The lower the value of the coefficient of friction the what resistance to sliding?
The lower the value of the coefficient of friction, the lower the resistance to sliding. A lower coefficient of friction means less force is needed to overcome the resistance between two surfaces, making sliding easier.
Does aluminum have lower resistance than copper?
No, aluminum has a higher resistance than copper.
How can we design a circuit with less resistance to allow more current flow?
To design a circuit with less resistance for more current flow, you can use conductive materials with lower resistance, increase the thickness of the wires, and minimize the length of the wires. Additionally, using components like resistors with lower resistance values can also help reduce overall resistance in the circuit.
Two light bulbs are in series how much power is dissipated by each bulb?
this is not an easy question. Assuming these are incandescent lamps with tungsten filaments, we need to know the type and rating of the lamps (bulbs) and the voltage. Incandescent lamps are highly non-linear and vary greatly in resistance depending on temperature--at lower voltage, the temperature is lower and the resistance is less. The problem is finding the stable operating point at the lower voltage. Probably the easiest way to answer this is build the circuit and measure. As a general rule, if the two in series bulbs are equal wattage, each one will dissipate 1/3 of its rated wattage (at half voltage). So two 25W bulbs in series will each dissipate about 8W, or 16W total.
Which bulb will glow brighter two bulbs of rating 100w-220vand200w-220v are connected in a series to a supply of 22ov?
For a lamp to operate at its rated power, it must be subject to its rated voltage. The lower the voltage, the lower the resulting power. In fact, a small drop in voltage will cause substantial drop in power. Higher 'wattage' lamps have lower resistance values than lower 'wattage' lamps.So, if you put two lamps in series, the greater voltage drop will appear across the lamp with the greater resistance. In your example, that means the 100-W lamp will be subject to the greater voltage drop, and its loss of power will be less than that of the 200-W lamp. So the lower power lamp will be the brighter of the two.
The lower the value of the coefficient of friction what is the resistance to sliding?
The lower the coefficient of friction, the lower the resistance to sliding between two surfaces. A lower coefficient of friction means that it is easier for one surface to slide past the other with less force or effort required.
Do two light bulbs in a series circuit have the same brightness?
yes but they will each be less bright then if there was only one light bulb in the circuitAnswerIt depends on their power ratings. If they are different, then the lamp with the lower power rating will be the brighter. The reason for this is that lower power lamps have a greater resistance than higher power lamps and, so, a greater voltage drop appears across the lower power lamp, making them brighter.
What happens to resistance of the wire if the wire is short?
If the wire is short, its resistance will likely decrease. A shorter wire has less length for electrons to travel through, resulting in lower resistance according to the formula R = ρL/A, where R is resistance, ρ is resistivity, L is length, and A is cross-sectional area.
How does the thickness of wire affect the resistance?
Thicker wire has less resistance than thinner wire due to lower electrical resistance. Thicker wire allows more electrons to flow through it easily, resulting in less opposition to the flow of electric current.
What happens to the resistance of a filament if it is replaced by a shorter wire?
If a filament is replaced by a shorter wire, the resistance will decrease. Resistance is directly proportional to the length of the wire, so a shorter wire will have lower resistance. This is because there is less material for the electrons to travel through, resulting in less opposition to their flow.
How does resisitance affect currents?
The higher the resistance the less current can pass through therefore the current will be lower.
