We can reduce the supply voltage from the ohms law relation.......v=ir...
resistance is directly proportional to supply voltage...or.....we can control the resistance by the relation by R is directly proportional to l/a
l=length
a=area
Your measure resistance in OHMS ΩOhms.
The ohmmeter is usually used to measure the resistance of a given wire only.
wind resistance cannot be ignored in considering a simple pendulum. The wind resistance will be proportional to a higher power of the velocity of the pendulum. A small arc of the pendulum will lessen this effect. You could demonstrate this effect for yourself. A piece of paper attached to the pendulum will add to the wind resistance, and you can measure the period both with and without the paper.
You have to measure the voltage, and the current. The resistance is then calculated by using Ohm's Law.
used to measure low Resistance since it must reach a null.
Ohms measure electrical resistance. The resistance in ohms is the voltage divided by the current.
You can use a multi-meter to measure resistance. The specific portion of the meter for measuring resistance is called an ohmmeter.
Wheatstone bridge is used to calculate the resistance of unknown resistor in the circuit.
You can measure an unknown resistance by using a multimeter set to the resistance measurement function. Connect the unknown resistance in series with the multimeter and apply a known voltage across them. The multimeter will display the resistance value based on the voltage and current readings.
This question makes no sense. You are asking for resistance and then saying the resistance is 10 us. "US" is not a measure of resistance. The measure is called Ohms. Ohm's Law states that Voltage = Current x Resistance Hence Resistance = Volts divided by Amps.

Inertia is an objects resistance to change in motion. Frictional forces resist motion.
