In the circuit below calculate the CURRENT in the resistor i
In the circuit below, calculate the CURRENT in the resistor (in mAmps) if R1 = 1,089 Ohms and V1 = 10 V. Assume that the forward bias voltage is 0.7V and that the saturation current is zero. Give the answer to within 5%.
SR D1Solution
Apply KVL to the circuit
V1-IR1-Vd=0
IR1=V1-Vd
I= V1-Vd/R1
given that V1=10 volts , R1=1089 ohms and Vd=0.7
then I= 10-0.7/1089
I=8.53milli amperes
Therefore I= 8.53 mA
