Q1 (ii) A light emitting diode (LED) with a forward voltage drop of 1.8 V, a resistor and a 6 V battery are all connected in series such that the LED is forward biased. (a) Determine the resistor value if the LED current is to be 35 mA. (b) An additional resistor is to be placed in the circuit in order to increase the LED current to 60 mA. Draw the circuit with the additional resistor and calculate its value.
