Another effect is loading on the output. Take, for example, a voltmeter with an input
impedance of 1 MΩ. If R
read? It should be 5 V since the transistor is in cutoff, but R
input form a voltage divider as shown in Figure 3-16. The actual measured voltage
would be 2.5 V. This is termed “loading”.
C
is 1 MΩ and the transistor is in cutoff, what voltage will be
