A p-n-p transistor is used in common emitter mode in an amplifier circuit.

A p-n-p transistor is used in common emitter mode in an amplifier circuit. When base current is changed by an amount ∆Iв, then the collector current changes by 4 mA. If the current amplification factor is 60, then the value of ∆Iв is,
