Between March and July 2020 the power supply was stable due to reduced demand during the COVID-19 lockdown, [33] but on 12 July a new round of level 2 load shedding began due to the breakdown of generating units. [34] During the winter of 2023, the country experienced Stage 6 blackouts, shaving a projected 2% off the country's GDP. [35]
A typical example of the use of a common-emitter amplifier is shown in Figure 3. Figure 3: Single-ended npn common-emitter amplifier with emitter degeneration. The AC-coupled circuit acts as a level-shifter amplifier. Here, the base–emitter voltage drop is assumed to be 0.65 volts.
Emitter bias. When a split supply (dual power supply) is available, this biasing circuit is the most effective. It provides zero bias voltage at the emitter or collector for load. [clarification needed] The negative supply V ee is used to forward-bias the emitter junction through R e. The positive supply V cc is used to reverse-bias the ...

For an NPN open emitter output, the collector is connected to the positive voltage rail, so the emitter outputs a high voltage when the transistor is on and is hi-Z when off. For a PNP open emitter output, the collector is connected to the low voltage supply, so the emitter outputs a low voltage when the transistor is on and is hi-Z when off.
Statewide, utilities could see a roughly $835 million gap between the cost of replacing the state's estimated 100,000 lead lines and the federal funding available for the work, an advocacy group says.
