Question

(a) Calculate the equivalent resistance of the R_1 and 5.00-Ohm resistors connected in parallel. Ohm (b) Using the result of part (a), calculate the combined resistance of the R_1, 5.00-Ohm and 4.00-Ohm resistors. Ohm (c) Calculate the equivalent resistance of the combined resistance found in part (b) and the parallel 3.00-Ohm resistor. Ohm (d) Combine the equivalent resistance found in part (c) with the R_2 resistor. Ohm (e) Calculate the total current in the circuit. A (f) What is the voltage drop across the R_2 resistor? V (g) Subtracting the result of part (f) from the battery voltage, find the voltage across the 3.00-Ohm resistor. V (h) Calculate the current in the 3.00-Ohm resistor. A

Explanation / Answer

a) ( R1 x 5 )/ ( 5 +R1)

b) ( R1 x 5 )/ ( 5 +R1) + 4

c) ( R1 x 5 ) / (5+ R1) +4 ) ( 3) / ( R1 X 5 / 5 + R1 + 7) = 3 ( {R1 x 5 }/ {5 + R1 } + 4 ) / ( 5R1/5+R1 +7)

d) R2 + 3 ( {R1 x 5 }/ {5 + R1 } + 4 ) / ( 5R1/5+R1 +7)
