Challenge Problems
Push your limits with advanced challenges
Design a current amplifier circuit with a specified output current of 100mA and an unloaded current gain of 10. Determine the required input current.
💡 Hint: Use algebra to rearrange the formula.
Given the loading parameters as R_O = 100Ω and R_in = 50Ω, and a source current of 4mA, calculate the effective output current and analyze how it differs from the unloaded case.
💡 Hint: Consider the parallel resistance formulas.
