Does the resistance of a wire depend on the cross section area of the wire?
Yes. The bigger the cross section, the lower the resistance.
How does a wire's cross section affect resistance?
If two pieces of wire are made of the same material and have the same length but different resistance, then the one with the greater cross section area has the lower resistance.
What is the cross sectional area of a wire?
If you slice a wire cleanly and then look at the cut end, you see a little circle at the end. The area of that circle is the "cross-sectional area" of the wire. The larger that area is, the lower the DC resistance of the wire is.
Does a wire with a diameter of 0.01 mm have lower resistance than a wire with 0.1 mm?
No, a smaller diameter wire has a higher resistance. The 0.01 mm wire will have 1/100 the cross-sectional area of the 0.1 mm diameter wire, therefore the resistance will be 100 times as high.
Why a hair dryer has a high- heat setting with a lower resistance than the low-heat setting?
Because a higher resistance would have resulted in more heat loss, but the higher is he current, the more energy is lost to heat. Therefore, a lower resistance would release more heat.AnswerPower is equal to voltage squared divided by resistance. So, for a given voltage, the lower the resistance the higherthe power.
How will read the humsn body resistance?
The resistance of a human body changes, you can divide it in 3 groups: dry body, semi-wet body (sweat,...) and wet body (in a swimming pool,...) the more wet the body becomes, the lower the resistance.
What is r lower for wet skin than for dry skin?
resistance for electricicty
Does the resistance of a wire depend on the cross section area of the wire?
Yes. The bigger the cross section, the lower the resistance.
Why has the greater electrical resistance in wet skin?
Wet things are provide less resistance to electricity
What is human body resistance to electricity if skin is wet?
human body resistance to electricity when skin is wet is 1,000 ohm and when skin is dry its resistance is 100ohm
How does a wire's cross section affect resistance?
If two pieces of wire are made of the same material and have the same length but different resistance, then the one with the greater cross section area has the lower resistance.
What type of wire increases when it is made thinner?
Since resistance is inversely-proportional to cross sectional area, the lower the cross-sectional area, the higher the resistance. So ALL types of wire exhibit this behaviour!
The larger the conductor the Higher the resistanc Lower the ampacity Higher the voltage Lower the resistance?
No. The larger the conductor the lower the resistance and the higher the ampacity.
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.
Is garelochhead a wet area?
is garelochhead in argyll scotland a wet area
How does wetness affect the resistance of your body?
Higher wetness lower resistance.
What is the area of Wet Moor?
The area of Wet Moor is 4,910,000.0 square meters.
