To turn on an IGBT, a __________ voltage is applied to the gate.

A voltmeter is used to determine the voltage across a resistive element in the circuit of Figure P2.77. The instrument is modeled by an ideal voltmeter in parallel with a 120-k? resistor, as shown. The meter is placed to measure the voltage across R4. Assume R1 = 8 k?, R2 = 22 k?, R3 = 50 k?, RS = 125 k?, and iS = 120 mA. Find the voltage across R4 with and without the voltmeter in the circuit for the following values:
Assumptions:
The voltmeter behavior is modeled as that of an ideal voltmeter in parallel with a 120- k? resistor.
