hi, can you help me with iii, iv and v? The figure below shows the circuit of a battery polarity tester using two lightemitting diodes (LED) X and Y and a resistor R. The LED's have a forward voltagedrop of 1.8 V and the reverse bias leakage current that can be assumed to be zero.Currents below 0.6 mA do not produce any visible light output from the LEDS and thelargest LED current allowed is 75 mA. The battery is connected between terminals Aand B.A oR = 1502本ンYBoi)If the positive terminal of the battery is connected to B and the negativeterminal to A, state which LED will be forward biased and hence glow X orY?ii)Calculate the current in the resistor R when the battery connected to A andB has a voltage of 6V.iii)What is the smallest battery voltage that can be tested?iv)What is the largest battery voltage that can be tested?v)What is the largest power the resistor dissipates?
