Question

Three resistors with color codes 1. Brown, Brown, Brown, 2. Red, Red, Red 3. Orange, Black, Orange are connected in parallel. A battery of voltage 4.5 V is connected to the resistors. a) Draw the circuit diagram. b) List the values of the resistors according to color code. c) Calculate the equivalent resistance 1st Digit d) Find the current through each resistor e) Add the currents through each resistor to find the total current and use the voltage to find the equivalent resistance 0 i 2 2nd Dipit No of Zeros Tolerne Black Brown Red Orange Yellow Green Blue Violet Gray white 3 4 5 Fourth Band None 120% Silver +10) Gold +39 Red 7 S 9 Resistor Chart I Example: Red, Brown, and Yellow: R-21,0000 or 21x100

Answer 1

RI نم R3 V B) R, = 11x10 - 1100 R2= 22x10² =) 2 2002 R3 = 30x10² 30000 L I (C) 1 Req R. R3 L + Ri ㅗ 110 tt 2200 30000 Req=104.4k d) I=v 4.5 0.041 A R. In=Y 4.5 0.002045 A 110 R2 I3 = x 2200 = 4.5 30000 o.coolS A @ I Total = I + I₂ + Iz 0.041+ 0.002045 + 0.00015 0.043195 A V I Total 0:043195 Rent = 4.5 104.30
