So back to our circuit, if we have 5 volts and want 3V from it, we use the formula above. If we use a 10KΩ as our R1resistor, plugging in the values, we get R2= (V)(R1)/(VIN- V)= (3V)(10KΩ)/(5V - 3V)= 15KΩ. So we can use a 15KΩ resistor as our R2resistor...
Ohm's law is an important mathematical formula that electricians and physicists use to determine certain measurements in a given circuit. The formula is: V=I×RV=I×R where V is the voltage, measured in volts, I is the amount of current measured in amps or amperage and R is the resistan...
The INA233 has a power accumulator built into the device, which records the sum of the power measurements, number of measurements, and number of times the sum register has rolled over. Here's how the part works, from single measurement to accumulated power: The voltage ...
The best approach is to calculate the ON/OFF time of the transistor which yields maximum stable voltage across the output, meaning we need to make sure that the inductor is optimally switched such that it’s neither switched ON too quickly which might not allow it to discharge optimally, and...
Knowing the currents through the resistors, it is easy to now calculate the voltage across our open circuit node. The voltage between the two load connection points can be figured from either of the battery’s voltages and the nearest resistor’s voltage drop: ...
Turn on the voltmeter and set the scale to measure "Volts DC." Place the black voltmeter probe on the electrical joint between the second wire and the 1-kiloohm resistor. Place the red voltmeter probe on the electrical joint between the two resistors. The voltage across the resistor will be...
value of the resistance is much greater than the internal resistance of the ammeter, the voltage divided by the ammeter is very small, then the voltage measured by the voltmeter is close to the voltage across the resistor, so the internal connection method is suitable for measuring large ...
Young electronic hobbyists and enthusiasts are often confused and wonder how to calculate LED and its resistor in a circuit, since they find it difficult to optimize voltage and current through the group of LEDs, required to maintain an optimum brightness. ...
How much current flows through a 10-ohm resistor when it is connected across a 12-V battery? When a voltage of 12 V is applied to a resistor, a current of 2.5 A passes through it. What is the resistance of the resistor? In ...
At this point in the measurement system, waveform data from the modules is used to calculate any power quality parameter desired. Some of these calculations are fairly simple while others are complex calculations aggregated over several cycles, seconds, or minutes to determine the ultimate quality. ...
