The more current a voltmeter draws from the circuit under test, the more the measured voltage will sag under the loading effect of the meter. This is similar to a tire-pressure gauge releasing air out of the tire being measured: the more air released from the tire, the more the tire''s pressure will be impacted by the act of measurement.

$begingroup$ Hi @Petr it''s the same principle in that the circuit uses an inductor to store energy in the magnetic field. In the case of a boost regulator, the arrangement of components (inductor, diode, capacitors) are a little different. In a boost regulator, higher voltage is produced when the switching FET connects/disconnects the …

How to Increase Current in a Circuit?
To put it simply, voltage can be thought of as the pressure of the electrons in a circuit, while current is the flow of those electrons. The higher the voltage, the more forcefully electrons will flow through the circuit. There are two main ways to apply voltage: using a battery or using an AC power source. Batteries are the most common way to …

Some devices will work about the same at any battery voltage above a minimum threshold, and draw about the same current regardless of voltage. All of the batteries in series will get depleted at the same rate regardless of how many there are, but the level of depletion required to make the device unusable will be extended by having …

To absolutely maximize solenoid current without regard for battery life, set ratio of battery time to "shorting time" so that the battery is drawn down to about 4.5 volts. That will draw maximum power out of the battery, even though it will cause the battery to waste about half of its energy heating itself.
