Question

1. Given three resistors R₁ = 4 ohms, R₂ = 6 ohms, R₃ = 8 ohms and a 12 volt battery source. Construct a schematic diagram of the third resistor in parallel to the series combination of the first and second and resistor.   

2. Solve for total resistance, total current, and the voltage through each resistor.

                                                                                                      

3. Determine the relationship between the area and the frequency in an AC generator if all the variables are kept constant.

Answer 1

R2 2 Col O R = 42 R3 آے R₂ = 62 R₂=82 E=12v Portal I Total Resistance Circuit diagram R, and Re are in Series Rie= R + R₂ -4+62 Riz = 102 Riz and R3 are parallel Riotal Rız X R₃ RietRg Riotal = 10x8 2 10+8 Hence Rrotal = 4.44.2

Part (6) Total Current (2) 1. A 12 4.44 Rrotal Hence, I = 2.70A Part (0) Voltage Hence, [ V3 = 12V through Ra Current in R3 Is = V₂ 12 A R₃ 8 Iz = 1.5A Correntin I, and Iz I - 12 2.70-1.5 A "I , = Iz = 1.2A Voltage through Ri ܝܠ ܐ Vi= I, R = 1,2*4 = 4.8 V = 4.8V Hence vis Voltage through Rz V₂ I R₂ 1.2 x 6 Hence V2 = 7.2 V
