Current sensing resistor has higher accurate value when giving in a load because heat will alter the resistance of a resistor even a precision resistor but not a current sensing resistor.

Difference between current sense resistor and normal resistor. The resistor may be located in the circuit or in the meter. It will have values from zero to maximum value rated. One of best difference amplifiers for measuring the voltage across the sense resistor when the desired measurement point is outside of the op amps supply rail voltage is the texas instruments ina149 click to view data sheet.

Normal resistor precision resistor and current sensing resistor they are all resistors but they are all different. Shunt resistor current sensing. When measuring current with a shunt resistor what side of the load do you put it on.

Normal resistor precision resistor and current sensing resistor they are all resistors but they are all different. Resistors are usually of two types fixed and variable resistors. They are characterized by a resistive layer on a ceramic base.

It senses current by converting it to a low value voltage which is read by a voltmeter. Advantages and disadvantages of these methods are also mentioned. Although their appearance might be very similar their properties and manufacturing process are very different.

What is the difference between a resistor and a variable resistor. The ina149 is a precision unity gain difference amplifier with a high common mode rejection ratio cmrr for high input common mode voltage cmv applications. A good understanding in resistors is required in fields such as electronics process engineering and electronic parts manufacturing.

Resistance of a fixed resistor cannot vary like in the case of a variable resistor. The figure 1 depicts high side shunt resistor based current sensing. Normal resistor is of fixed value with some tolerance variable resistor is potentiometer pot.

Precision resistor has high accurate value than normal resistor. A resistor is an electronic component which offers or implements electrical resistance. Precision resistor has high accurate value than normal resistor.

Thin and thick film resistors are the most common types in the market. A current sense resistor is a resistor used to sense the current in a circuit and is usually a low value and may be a 4 terminal resistor. It is widely used as a circuit element.

Current sensing resistor has higher accurate value when giving in a load because heat will alter the resistance of a resistor even a precision resistor but not a current sensing resistor. This page compares shunt resistor current sensing vs hall effect current sensing and mentions difference between shunt resistor current sensing and hall effect current sensing. If youre amplfying the voltage drop across the sense resistor and digitizing that voltage it makes a difference.
