Total Charging Time Solution

STEP 0: Pre-Calculation Summary

Formula Used

Total Charging Time = Emitter Charging Time+Collector Charging Time
τ_ct = τ_e+τ_c
This formula uses 3 Variables

Variables Used

Total Charging Time - (Measured in Second) - The Total Charging Time in a BJT is the duration for both emitter and collector currents to reach a substantial portion of their final values upon transistor activation.
Emitter Charging Time - (Measured in Second) - Emitter charging time is defined as drift in the motion of the charged particles induced by a field when you forward bias the emitter junction you get a large diffusion.
Collector Charging Time - (Measured in Second) - Collector charging time refers to the time taken for the minority carriers in the base region of a BJT to be swept out of the collector region after the transistor is turned off.

STEP 1: Convert Input(s) to Base Unit

Emitter Charging Time: 5273 Microsecond --> 0.005273 Second (Check conversion here)
Collector Charging Time: 6.4 Microsecond --> 6.4E-06 Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

τ_ct = τ_e+τ_c --> 0.005273+6.4E-06

Evaluating ... ...

τ_ct = 0.0052794

STEP 3: Convert Result to Output's Unit

0.0052794 Second -->5279.4 Microsecond (Check conversion here)

FINAL ANSWER

5279.4 Microsecond <-- Total Charging Time
