Problem 2: Consider controlling the Omron G5LE-1 5VDC power relay, shown below, using in the following circuit. A relay has windings that when energized cause a magnetic field, which mechanically closes the contact side of the relay, so it acts as an electronically controlled switch. One benefit of a relay is that the switch on the contact side is electrically isolated from the coil on the control side of the relay. This advantage of electrical isolation comes at a cost. Relays do not switch states quickly like transistors. Based on its data sheet, the Omron G5LE-1 5VDC has a coil resistance of 632 (at DC, consider the coil side of the relay as a resistor). Select the base resistance to ensure the P2N222A BJT is deep into saturation when the relay is energized (meaning current is flowing through its windings). onerate the Omron G5LE-1 at up to 130% of its rated voltage of 5VDC in its
