When a series LED connection is in question, you will just need to replace the "LED forward voltage" with "total forward voltage" in the formula, by multiplying FV of each LED by the total number of LEDs in the series. Suppose there are 3 LEDs in series then this value becomes 3 x ...
A multimeter is a measurement tool absolutely necessary in electronics. It combines three essential features: a voltmeter, ohmeter, and ammeter, and in some cases continuity. A multimeter allows you to understand what is going on in your circuits. Whenever something in your circuit isn’t working...
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...
Switch off the motor, and then disconnect one of the wires powering the motor. Attach your ammeter or digital multimeter set to measure DC current; attach it between the motor and the detached wire. Always wire ammeters in series with a circuit, placing them between the power source and the...
You might have paid more attention to the charging system gauge or warning light afterward. The amount of electrical current that the charging system provides to your vehicle's battery is monitored by either a voltmeter, which measures the voltage in the charging system, or an ammeter, which ...
Any short or open circuit or wrong connection can cause a sudden surge of voltage that will damage electronic parts. Never make or break any connection while the engine is running. Checking alternator output using an ammeter in series with the charging system should be done only by an auto-el...
I have not tryed this practically, but I want to know how to connect this two circuit I mean first circuit's upper module with the second's upper and first's lower with seconds lower? What should be the rating of the woofer and twitter. what should be the maximum load of the ...
(that of the ammeter) was introduced into the circuit. When we plot load voltage vs current, this does not matter since the measured current is for the total circuit resistance and corresponds to a matching load voltage measurement. However, we should certainly be asking questions as to why ...
For this circuit, we need 2 other sources of power. We need to connect power to the source of the drain of the MOSFET so that it can power on a load, which in this case in an LED. So we connect positive voltage to the anode of the LED and connect the cathode of the LED to th...
Voltage is measured across the terminals of the power source (just as measuring the height of the overhead tank). Current is measured inside the circuit (similar to measuring water with a flow meter). Current is measured using an ammeter, which is included in a multimeter. Current Measuring ...
