When measuring resistance where does the red cord go?

For simple resistance measurements it usually doesn't matter.

What is excessive electrical resistance?

High resistance means insulation

What is the difference between on and off state resistance?

On Circuit Resistance = Close to the total load Resistance. Off Circuit Resistance = Near Infinitive High Resistance.

Is high electrical resistance good or bad?

electrical resistance is when something resists the electrical current .. eg rubber hope it helped

What happens when skin resistance is high?

High skin resistance can produce severe skin burns but prevent the current from entering the body

Does plastic have a high resistance?

Yes, it has a high resistance as it is an insulator.

What are the Limitation of meter bridge?

Some limitations of a meter bridge include: Limited accuracy due to human error in taking measurements. Restricted use in measuring resistance values that are too high or too low. Sensitivity to external factors like temperature and vibrations, which can affect the readings. Inherent resistance in the connecting wires can introduce errors in the measurements.

Why do you use a meter bridge for measurements rather than a voltmeter and ammeter?

A meter bridge is used in some cases for precise resistance measurements. It can be more accurate than using a voltmeter and ammeter because it eliminates errors from contact resistance and internal resistance of the instruments. This method allows for more accurate determination of resistance by comparing two resistance values directly.

How much voltage is used to measure resistance?

The voltage needed to make a resistance measurement varies in proportion to the Ohms value being measured. Resistance measurements in the order of thousands and up to one Megohm are low enough to be made with a 1.5 volt or similar cell. However, resistance measurements in the order of hundreds to thousands of Megohm will require a higher voltage of up to 500 Volts DC. A Megger is a device that uses hundreds of volts to make resistance measurements.

What are electrical measurements based on?

voltage (volts) current (amps) resistance (ohms)

Do Dead batteries have high internal resistance?

yes, batteries have high internal resistance. The higher the resistance the lower power you get out of the batter. Therefore if you no power you have very high resistance.

How high is your body resistance?

Your body resistance is high- hard to push electrons through.

What attitude led to these difficulties?

The attitude of resistance to change and inflexibility likely led to these difficulties. Embracing a more open-minded and adaptable mindset could help in overcoming the challenges.

What is high resistance and low resistance?

Low resistance lets electrons through easy, and high makes it harder for them to pass. Basically electricity is harder to flow through high resistance and vice versa.

What is high resistance what is low resistance?

Low resistance lets electrons through easy, and high makes it harder for them to pass. Basically electricity is harder to flow through high resistance and vice versa.

What are 3 measurements are used in electricity?

Three measurements used in electricity are voltage (measured in volts), current (measured in amperes), and resistance (measured in ohms). These measurements are essential in understanding and analyzing electrical circuits and devices.
