What is the value of amperes for 100 volts at constant resistance?
V = I*R, so take 100 volts and divide it by the value of the resistance to get the current. Current is measured in amperes.
State 3 functions of wheatstone bridge?
Wheatstone bridge is used to calculate the resistance of unknown resistor in the circuit.
How to measure the root mean square value of MESURED voltAGE in convential voltmeter?
A conventional voltmeter displays 0.707 of the peak voltage when it measures AC.In doing so, it displays the RMS value of the measured voltage IF the measured voltage is a sinusoid.If the measured voltage is not a sinusoid, then its peak value is 1.414 times the displayed number, andyou have to calculate the RMS based on the waveform.
What happens to the total resistance of a series circuit when another resistor is added?
Simply put, the purpose of a resistor is to 'resist' the flow of current. Ohm's Law tells us that for a given voltage, the larger the resistance, or value of that resistor, the lower the current that will flow. Ohm's Law states that I (current) = E (voltage) / R (resistance) - where current is measured in amps, voltage is measured in volts and resistance is measured in ohms.
What should be the resistance value of healthy earth pit?
what is the resistance value of a healthy earth pit
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.
Is there any difference in measured and calculated value of resistance?
yes , there is a difference because there is a tolerance
What is the value of amperes for 100 volts at constant resistance?
V = I*R, so take 100 volts and divide it by the value of the resistance to get the current. Current is measured in amperes.
How do you calculate percentage error for density of pennies?
Percent error refers to the percentage difference between a measured value and an accepted value. To calculate the percentage error for density of pennies, the formula is given as: percent error = [(measured value - accepted value) / accepted value] x 100.
How do i find the current after it passes through a resistor?
Current can be measured with an ammeter. If you want to calculate it from other values, you will quite often use Ohm's Law (just divide voltage by resistance, if you know the resistance value of the resistor) - or perhaps a combination of Ohm's Law and Kirchoff's Laws.
State 3 functions of wheatstone bridge?
Wheatstone bridge is used to calculate the resistance of unknown resistor in the circuit.
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 can you calculate the difference between measured and calculated value?
A simple subtraction. Take the smaller from the larger
What the function of tolerance for resistor colour code?
Tolerance indicates how much the measured value of a resistance is different from its theoretical value, and it is calculated using percentages.
What is the difference between measured and calculated?
A measured value is one that is directly obtained from the environment, such as using a scale to weight something. To calculate a value is to figure it out using other values. For example, if you know the distance something traveled and the time it took, you can calculate its speed.
A resistor Connected to a 9 Volt supply dissipates 3 watts calculate the value of the resistance?
about 27ohms
How do you Match the resistance for gm passkey?
you have to have the origial key .measure resistance across pellet in key ,get resistor of same value ,install across connection below steering colum ,wala
