But the maximum collector current will be determined by supply voltage, 470ohm resistor, LED voltage drop and Vcesat. That is: Ic-max=(5-Vled-Vcesat)/470 Your max collector current can be about what you measured, abt 8mA. If you want 100mA collector current you should first set PS current limit above 100mA and reduce 470ohm resistor.
amplifier
With energy, it isn''t possible to get a free lunch. It''s relatively easy to amplify a microampere signal up to milliamperes, but that''s because the extra current comes from some type of power supply. This doesn''t work when the signal you''re trying to amplify is the power supply.. You might be able to use a transformer to trade current for voltage.
Do transistors actually amplify the current?If yes,then how?
If we wish to amplify 1 amp up to 10 amps, then we must have a power supply available that can handle 10 amps in addition to the original input signal, unless we use a common collector circuit and then we need a power supply that can handle at least 9 amps (the emiter current is the sum of 1+9 amps approximately).

Assuming, your battery can sustain the current before your regulator (boost significantly increase the input current). Let say you have a 48V 13Ah battery, it will approximately (ideal) to 624Wh. Your motor is 1800W meaning that in the ideal case, your battery will last 20 minutes. No matter what regulator you place in between, you will NEVER
How does a battery amplify current
A transistor can amplify because the collector current is very sensitive to changes in the voltage at the base, especially between 0.5 and 0.7 volts of base voltage. For example, a 1% change in voltage at the base can result in a 100% change or more in the current at the collector.

Two 1.5v batteries in parallel will increase amp hours, meaning if a tiny motor current draw is 2amps, the battery will last 1 hour, but since it is in parallel now last 2 hours. Now you can lower the resistance of your load, or connect another load in parallel (thus drawing more current), and still have your battery last the same amount of time.

How does a transistor act as an amplifier considering energy
The main thing a "source" does is fix the current (in the case of a current source) or the voltage (in the case of a voltage source) to a specific value. For example, a lithium-ion battery acts like a voltage source. If you connect a resistor across the battery terminals, the battery will supply current to hold the voltage more-or-less constant.

6 FAQs about [Can batteries amplify current ]
Why do batteries vary in size and voltage?
Batteries vary both in size and voltage due to the chemical properties and contents within the cell. However, batteries of different sizes may have the same voltage. The reason for this phenomenon is that the standard cell potential does not depend on the size of a battery but rather on its internal content.
How do op amps work?
The Op Amps control the battery discharge current and voltage, functioning in the same manner as they do when the battery is being charged. The boost converter boosts the battery voltage to VDC, which is usually 12 V. Figure 2. Battery Test Equipment Typical Amplifier Configuration
How does a battery work?
The two electrodes are each submerged in an electrolyte, a compound that consists of ions. This electrolyte acts as a concentration gradient for both sides of the half reaction, facilitating the process of the electron transfer through the wire. This movement of electrons is what produces energy and is used to power the battery.
Which op amp is best for a high voltage battery?
Assuming the temperature rises from 25°C to 85°C and the battery voltage is 4 V, we can easily calculate the real world error from one of our low-offset and low offset drift Op Amps, the TLV07. a precision Op Amp similar to TLV07 is an ideal Op Amp to meet the system output current and voltage error requirements.
What is the relationship between current and voltage?
where I is the current, k is a constant of about 1.3, t is the time the battery can sustain the current, and Qp is the capacity when discharged at a rate of 1 amp. There is a significant correlation between a cell's current and voltage. Current, as the name implies, is the flow of electrical charge.
How does temperature affect battery performance?
The rate of side reactions can be slowed by lowering temperature. Warmer temperatures can also lower the performance of the battery, by speeding up the side chemical reactions. Primary batteries become polarized with use. This is when hydrogen accumulates at the cathode, reducing the battery's effectiveness.
