What is a fixed resistor measured in?
Resistance is measured in ohms.
What is the function of a variable resister in an electrical circuit?
A variable resistor usually has three terminals, one of which is connected to the 'wiper' by which means its resistance is measured. By using all three terminals, we can control the potential difference in a circuit. When used in this way, we call the variable resistor a 'potentiometer'. By using two of the three terminals, one of which must be connected to the variable wiper, we can control the current passing through circuit. When used in this way, we call the variable resistor a 'rheostat'.
Why connect a 100 Ohm resistor to the two terminals of a capacitor If the voltmeter doesn't turn to zero would be better to use a larger resistor?
We can guess that the resistor is used for discharging the capacitor's plates. Generally we short the two terminals on a capacitor to discharge it fully. A resistor will take more time to do this than shorting-out the terminals: the higher the resistance, the longer the time that will be taken to discharge a capacitor fully.
Can you measure the internal resistance of dry cell using multimeter?
Well, you do use a multimeter to measure it, but not directly. You need at least one other thing besides the multimeter and the dry cell. Here's a simple way to do it: -- Take a resistor. With the meter set to measure resistance, measure the resistor's value. Call that 'R'. -- With the meter set to measure voltage, measure the voltage of the dry cell. Call it 'V1'. -- Connect the resistor across the dry cell. Measure the dry cell's voltage again. Call it 'V2 ' this time . V2 will be less than V1 . The internal resistance of the dry cell is R times (V1 - V2) / V2
Is a voltmeter a linear scale?
This is because the resistance is measured by applying a fixed voltage to the resistor and measuring the current. Since I = V/R, the current/resistance relation is non-linear.
Can you calculate the resistance of a component using a meter and a resistor?
yes you can! you can use a multimeter and a resistor.
Why does resistance value measured using multimeter differ from one decoded using colour band?
The difference in resistance value measured using a multimeter and one decoded using color bands on a resistor could be due to imprecision in the resistor's color bands, aging of the resistor affecting its resistance value, or inaccuracies in the multimeter's measurement. It's essential to consider the possibility of tolerance levels in resistors, which can lead to variations in measured values.
What is a fixed resistor measured in?
Resistance is measured in ohms.
Is resistor measured in amps?
No, resistors are measured in ohms, not amps. Ohms represent the resistance offered by the resistor to the flow of current, whereas amps (amperes) represent the measure of current flowing through a circuit.
Can you use the multimeter to measure the resistance of a resistor when there is current passing the resistor?
A: NO the only way is to lift one lead and measure.
What instruments used in measuring current and voltage?
Multi meterAnswerInstruments that measure current are called ammeters, and instruments that measure voltage are called voltmeters. An instrument that measures resistance is called an ohmmeter. Each of these functions can be combined into one instrument, called a multimeter.
How is an multimeter connected to take a measure?
Multimetres are generaly used to measure the following quantities. Voltage: multimeter is connected in parallel with the Load; Current: multimeter is connected in series with Load; Resistance: the resistor must be taken out of the circuit first, then, the probes from the multimeter are connected across the resistor,
Functions of a multimeter?
A multimeter combines the functions of an ammeter, voltmeter, and ohmmeter and, so, can be used to measure current, voltage, and resistance by selecting the appropriate scale/setting.
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.
How do you test to identify a bad resistor?
To test a resistor, you can use a multimeter set to the resistance measurement mode. Connect the multimeter leads to the resistor terminals and check if the resistance reading matches the labeled resistance value on the resistor. If the reading is significantly different, the resistor may be faulty. Additionally, visual inspection for physical damage or discoloration on the resistor can also indicate a bad resistor.

What does resistor perform?
A resistor's resistance is measured in ohms. The higher the resistance the less current will flow with a constant voltage applied across the resistor. In terms of Ohm's Law Voltage = Current x Resistance.
