What is the resistance value of a 2.2 megohm resistor?
A megohm is 1,000,000 ohms, so 2.2 megohms is 2,200,000 ohms, often abbreviated to 2.2M, or 2.2Mohm, or 2M2.
What is the resistance value of 2.2 megohm resistor?
A megohm is 1,000,000 ohms, so 2.2 megohms is 2,200,000 ohms, often abbreviated to 2.2M, or 2.2Mohm, or 2M2.
What happens to the value of insulation resistance of a cable when the cable gets older?
Insulation resistance should be approximately one megohm for each 1,000 volts of operating voltage, with a minimum value of one megohm. For example, a motor rated at 2,400 volts should have a minimum insulation resistance of 2.4 megohms.
Is resistor measured in amps?
No, a resistor isn't measured at all. A resistor has a quality called "resistance" - and that value is measured. Resistance is measured in Ohms.
What are resistor values defined by?
Resistor value is defined by the Resistance the resistor offers in Kilo ohms/ohms value given by color codes on the resistor.
What do the colours on resistor mean?
It's a code to tell you the value of the resistance of the resistor.
Why resistor should disconnected from the circuit when measured the value of resistor?
if not disconnected you will measure the resistance of the circuit in parallel with the resistor.
When the resistor removed from a parallel connection of the circuit whether the resistance increase or decrease?
if we remove a resistor from the parallel connection the effective resistance value will be increased.
How does a megohm meter work?
The megohm meter (or megger) passes the 500, 750, 1000 volts to the wire that needs to be checked. According to ohms law R=V/I, the current in the returned voltage is measured and divided by the resistance (inside the meter). So when the current is high (i.e not properly insulated or leaking), the resistance value will drop otherwise resistance will be high.
What does a fixed resistor do in a circuit?
It resist the flow of current according to the resistance value.
2 resistors unequal value are in parallel. Would the power dissipated by the resistor with larger ohmic value be greater than the power dissipated by the resistor of lesser value?
No, because the power dissipated in a resistor is proportional to the square of the current through the resistor but only directly proportional to the resistance of the resistor (I^2 * R) and the current through the lower value resistor will be higher than the current through the higher value resistor, the lower value resistor will usually dissipate more power.
What is the resistor color code and how is it used to identify and select resistors?
The resistor color code use to help to identify the resistance of the resistor. There are four color in the resistor that help to identify the resistance of the resistor. The first and second color represent the numerical value of the resistor. The third color represent the multiplier. The four color represent the tolerance.
