Calculate the resistance in ohms of a resistor when the voltage is 5 volts and the current is 0.2 amps.The resistance R is equal to 5 volts divided by 0.2 amps, which is equal to 25 ohms:R = 5V / 0.2A = 25ΩVolts to ohms calculation with watts...
Photo: Measuring resistance with a multimeter. Using a multimeter like this one, you can automatically find the resistance of an electronic component; the meter feeds a known current through the component, measures the voltage across it, and uses Ohm's law to calculate the resistance. Although ...
Assume you want to carry out the cold-junction compensation at 25°C. Then a J-type thermocouple generates an output voltage change of 52µV/°C. The PT100 element creates a change of resistance of 0.388Ohm per °C. So a current of 52µV / 0.388R = 134µA must...
immediately upon arrival, it is important to protect it against external factors likemoisture, high temperature and impurities in order to avoid damage to the insulation. Before the motor is put into operation after a long period of storage, you have to measure the winding insulation resistance. ...
Two resistors of 15 and 30 are connected in parallel. If the combination is connected in series with a 9.0 V battery and a 20 resistor, what is the current through the 15 resistor? A) How does current change for resistors in series? B) What is the equivalent resistance for resistors in...
Step 1: Double Confirm the Resistance of the Resistor Even thought the value of the resistance is printed, you still need to confirm whether the actual resistance is the same as shown. Most resistor has 10% tolerance in their actual value, but it still depends on the type of resistor you...
Electronics is fairly new to me and there are things I do not understand, but I want to learn. Right now I am facing some difficulties in fully understanding how I should proceed when calculating the values. http://www.ti.com/lit/ds/symlink/tl494.pdf...
Q1:when calculate the max voltage drop of bootstrap capacitor,I do not understand the last item of the formula:Vcesat.Why subtract Vcesat??? Q2:The article shows how to calculate the value of bootstrap resistor,but how to know the charge current?The charge current ...
Determine the total number of resistance in the circuit. You measure resistance in ohms, which is expressed using the Greek letter omega. If you measure that there is a resistor with 3 ohms of resistance in this circuit and another with 2 ohms of resistance, that means that the circuit has...
To properly calculate the resistance value of your pull-up resistor, you’ll need to know what logic type your circuit is using to operate. The logic family that your circuit uses will dictate the resistance value your pull-up resistor will need. There are several types of logic. Here are...
