I need to amplify a low current (50mA) voltage signal to a higher current without changing the voltage. The voltage output operates a meter that requires around 700mA to move the needle. The voltage range is from 2.3 to 12.8 DC. I have read that this can be done by connecting the output to the Base of a NPN transistor.

When electric current flows through a wire, it creates a magnetic field. You can prove this to yourself with a magnetic compass (see the Science Buddies Abbreviated Project Idea Using a Magnet as an Electrical Current Detector, …
A transistor can be used to increase current. You''ll have a low current path, from base to emitter in an NPN, and a higher current path from collector to emitter. The collector current will be a multiple of the base current if the circuit allows it. That means that the voltage source at the collector side must be high enough, and the load ...

I guess that the current is limited by the internal impedance of the battery. Hahahaha -- look here-- the battery is rated for 0.5mA continuous with peaks of 5mA.No wonder it gets hot. And the internal impedance almost certainly limits the current to something that is quite likely safe for the LEDs.
An LED bulb has a life span of 50,000 hours, whereas the CFL has a lifespan of 8000 hours and the incandescent lasts a mere 1200 hours. The LED bulb is the most durable, easily withstanding rough treatment such as jarring and bumping. The incandescent light bulb has little tolerance to the same treatment since the filament and glass can easily ...

To enhance the resolution of current measurements with the ACS712 sensor, you can amplify the sensor''s output signal using an operational amplifier (op-amp) circuit. This can help increase the sensitivity and precision of the current readings. Can I use the ACS712 sensor for battery monitoring applications? Yes, the ACS712 sensor can be used ...
We tried connecting a 10Ω resistor to a 12V battery with a current flowing through the resistor of approximately 1.2A and calculated the wattage it used: P = V x I P = 12V x 1.2A P = 14.4W. If you want increased current, we can normally do this in two ways. Increasing the current, but in this case we need to use only a 12V power supply.
Additionally, there are ways in which batteries can amplify their voltages and current. When batteries are lined up in a series of rows it increases their voltage, and when …
extending battery life in future devices will require mastery of low quiescent current. This paper examines the role of low quiescent current in delivering the battery life essential for today''s and tomorrow''s wearable, mobile, and other smart, connected devices. Abstract 1 of 8
The higher the amps, the more power the battery can deliver. The amps rating of a car battery is typically listed as "CCA" or "cold cranking amps". This refers to the amount of current the battery can provide at 0 degrees Fahrenheit (-18 degrees Celsius) for 30 seconds while maintaining a voltage of at least 7.2 volts.

A transistor can amplify current, or voltage, or both, depending on how it is configured in the circuit. A bipolar transistor configured as ''Common Collector'' amplifies current, but not voltage. When configured as ''Common Base'' it amplifies voltage, but not current. In ''Common Emitter'' mode it can amplify both.
