Question
Consider the circuit shown in the figure below. (Assume R1 = 9.00 ?, R2 = 2.30 ?, and V = 7.00 V.) (c) Calculate the equivalent resistance of the combined resistance found in part (b) and the parallel 3.00-? resistor. (d) Combine the equivalent resistance found in part (c) with the R2 resistor. ? (e) Calculate the total current in the circuit. A (f) What is the voltage drop across the R2 resistor? V (g) Subtracting the result of part (f) from the battery voltage, find the voltage across the 3.00-? resistor. V (h) Calculate the current in the 3.00-? resistor. A
Explanation / Answer
a)Req=R2+(3||(R1||5 +4))=2.3+(3||(3.21+4))=2.3+2.12=4.42 o b)
