The unknown device consists of DCsources and resistors. Two measurements are made on the device. For measurement 1, a resistor R1of 18K ohm is connected between a and b, and a voltage V1of 54 V results. For measurement 2, a battery with voltage V2of 9 V is connected, and a current I2of 6.75 mA results. A)Find and sketch the Thevenin equivalent circuit of the device. The Thevenin components will be integers. B) If a 6K ohm resistor is connected to the device, what will be the current be (in mA)? The answer is an integer
