A 22k ohm and a 2.2k ohm resistor are connected in series and are used as a voltage divider in the circuit shown in Fig.Q2. Both resistors have the same power rating of 0.25 W.
(a) When the supply voltage is 60 V, what are the ammeter (in mA) and voltmeter readings (in V)?
(b) Can you raise the supply voltage to 90 V safely? (Note: you must provide your answer in lowercase) (yes/no)
(c) What is the highest voltage to which the supply voltage can be raised (in V)?
* Please provide your answers to four significant figures.
