举一反三
- when a transistor is in the forward-active mode, the collector current is constant with a constant base current
- When a BJT is in cutoff, the collector-to-emitter voltage is typically equal to _____ A: collector supply voltage B: collector current times collector resistor C: 0.3 Volts D: emitter voltage
- When a BJT is biased in the cutoff region the collector-to-emitter voltage is typically equal to （ ）. A: the emitter voltage B: the collector supply voltage C: 0.03 V D: the collector current times the collector resistor
- The current ratio is measured as: A: current assets minus current liabilities. B: current assets divided by current liabilities. C: current liabilities minus inventory, divided by current assets. D: cash on hand divided by current liabilities. E: current liabilities divided by current assets.
