What will happen to the resistance if the length of the conductor increase?
ERMM THE RESISTANCE INCREASES ) when longer
How much resistance in blown fuse?
INFINITE RESISTANCE Like taking your meter and holding the probes an inch apart in th air.
How does length affect the resistance?
If we increase the length, the resistance will increase and vice versa.
When tempratere increase resistance increase and when resistance increase current decrease why?
That's what "resistance" is all about: reducing the current for a given voltage. In fact, you can DEFINE resistance as voltage divided by current.
What should the ohmmeter read when the lead probes are touched together?
When the lead probes of an ohmmeter are touched together, the ohmmeter should read close to zero ohms, indicating a short circuit or very low resistance between the probes.
Should you increase voltage or resistance to increase flow in a circuit?
To increase (current) flow in a circuit you increase voltage (or decrease resistance). Ohm's Law: Current = Voltage divided by resistance
Does lowering resistance increase current?
Current is proportionally inverse to resistance and when the voltage is fixed, lowering resistance will increase the current
What is the advantage of four probe method over other conventional methods?
I assume you are referring to methods of measuring small value resistances, as in locating short circuits on a PC card. Two probe is the method used by standard ohm meters. This works OK for most resistance values, as the resistance of the leads & probes is much lower than the resistance being measured. But when the resistance being measured gets very tiny (e.g. a few milliohms) it fails as the resistance of the leads & probe are of the same order of magnitude and are in series with it. Four probe solves this problem by using two probes connected to a current source to drive the resistance and a separate two probes connected to a precision voltmeter calibrated in milliohms. The voltage drop in the leads due to the test current does not get measured by the calibrated voltmeter, as it does in two probe method. There is no voltage drop in the measurement leads as the voltmeter is high impedance.
What does it mean to increase the host's resistance?
To transmitted the increase
Will the resistance of a copper conductor decrease with an increase in the applied voltage?
If all environmental conditions remain constant then the resistance will not change appreciably with applied voltage, but the current will increase. An increase in current will raise the temperature of the conductor which will increase the resistance somewhat.
What is negative resistance region?
The region where resistance decreases with increase in temperature.
How do you decrease voltage?
Increase resistance
