Current and Voltage Relation: The current passes through a resistor in a circuit connected across a battery of the potential V is equal to the ratio of the supplied voltage and resistance. As we increase the potential of the battery, the current in the resistor d...
Two resistances are said to be in parallel if the one terminal of a resistor is connected to the one terminal of the other resistor, and a similar connection is made with their other terminals. In a parallel connection, the potential difference across each resistor is the same. The cu...
Since current always creates a magnetic field, there areHall Effectand other sensors that allow us to measure this field and thereby measure the current. It is also possible to connect a shunt resistor within the circuit itself and directly measure the current, as in the classic ammeter and cu...

There is 0.05 mA flowing through the resistor, and thereby also through the input pin down to ground. Again, use Ohm’s law to find the resistance of something with a voltage drop of 8.5 V and a current of 0.05 mA: The input impedance is 170 kΩ. That means a pull-up resistor for...
The VivoWatch 6 calculates your current altitude by sensing these changes in air pressure.(2) Advantages of calibrating the altimeter Severe weather conditions (such as during a typhoon) can affect the accuracy of the watch's altimeter. It is recommended to calibrate the altimeter during harsh ...
If your 401(k) plan offers limited investment choices, you may find more options available through an IRA. Consider different types of investments in the IRA, such as stocks, bonds, exchange-traded funds and mutual funds. Before deciding what to do with your 401(k) funds, you’ll also wa...
To receive the funds, you will need to talk to your plan sponsor, who might be a human resources representative at your workplace or a financial advisor assigned to the plan. "This is generally where the employee can find out about the employer's specific requirement and obtain the paperw...
a capacitor and resistor (both of unknown values "C" and "R") connected in series and I'm given a time constant value T for the circuit and I can choose to feed any input voltage signal into the circuit (DC or AC power through "Vin"), how do I find the valu...
When the maximum resistance of the sliding rheostat is approximately equal to theresistance of the resistorto be measured, a voltage divider circuit must be selected. When measuring with a voltmeter (ammeter), one must ensure that the measured data cannot exceed the maximum measurement value of th...
