Q3) A device has two sensors, one measuring the temperature and the second measure the current. The temperature sensor is a thermocouple gives output signal considered linearly proportional to the temperature between 0V and 20 mV for 0°C temperature and 150°C, respectively. Whereas, the current measuring sensor gives voltage proportional to the current between OV and 1V for 0A and 2A ,respectively. The temperature should not exceed 100°C and the current should be less than or equal to 1.2 A. The device should work only if the two mentioned conditions are both true. Design a circuit to make the device works according to those conditions, the device relay should get 5 V to switch it on, and OV make it off.

You are an electrician working on an overhead crane. The crane uses a large electromagnet to pick up large metal pipes. The magnet must have a minimum of 200 VDC to operate properly. The crane has an AC source of 240 V. You are given four diodes that have a peak voltage rating of 400 V each. These diodes are to be used to form a bridge rectifier to convert the AC voltage into DC voltage. Is the voltage rating of the diodes sufficient? To the nearest volt, what will be the DC output voltage of the bridge rectifier?

For the subsequent questions, please refer to the circuit below. Assume that the diode is ideal (e.g. the voltage across it is zero volts when it is ON) IK VINZI IN=IV (+) I Sv(t Jo Vo Suppose we assume the diode is ON, what is V. in volts? Suppose we assume the diode is ON, what is the resistor current I in mA? Suppose we assume the diode is ON, our assumption is correct because the condition ID>=0 will hold as lp will be (in mA)... Suppose we assume the diode is OFF, this is a wrong assumption because when we solve for Vp with the diode as an open-circuit, the condition VD<=0 will NOT hold as Vp will be (in volts)...
