Total Power Supplied in BJT Solution

Follow our step by step solution on how to calculate Total Power Supplied in BJT?

FIRST Step Consider the formula

P = V DD \cdot (I c + I in)

Next Step Substitute values of Variables

∴

P = 2.5V \cdot (5mA + 1.45mA)

Next Step Convert Units

∴

P = 2.5V \cdot (0.005A + 0.0014A)

Next Step Prepare to Evaluate

∴

P = 2.5 \cdot (0.005 + 0.0014)

Next Step Evaluate

∴

P = 0.016125W

LAST Step Convert to Output's Unit

∴

P = 16.125mW

How to Evaluate Total Power Supplied in BJT?

Total Power Supplied in BJT evaluator uses Power = Supply Voltage*(Collector Current+Input Current) to evaluate the Power, The total power supplied in BJT is equal to the product of the supply voltage of BJT and the total current. It is the power delivered to the transistor by the external power source, such as a battery or a power supply. This power is used to bias the transistor into the desired operating mode and to drive the input signal. The total power supplied to the BJT can be calculated as the product of the voltage across the BJT and the total current flowing through it. Power is denoted by P symbol.
