Design a current amplifier circuit with an input current of 1 mA and a target output current of 20 mA. What must the current gain be?
💡 Hint: Use the current gain formula to solve.
If a current amplifier has a current gain of 10 and experiences loading effects that reduce the output current by 1 mA, what will the effective output current be if the input current is 5 mA?
💡 Hint: Consider both current multiplication and any reduction due to loading.
