Question

. A series-parallel combination of resistors is created from 4 resistors, there is a 45 ohm resistor followed in series by a parallel combination of a 30 Ohm resistor on one branch, and a 10 Ohm and a 15 Ohm resistors in series on the other branch. The whole combination is attached to a 12 V battery. a) find the net resistance of the resistors to the current from the battery. b) What is the current in the 45 Ohm resistor. c) What is the voltage across the 45 Ohm resistor? d) What is the voltage across the parallel combination of resistors? e) Find the currents through each of the remaining resistors and the voltages across each resistor. f) Calculate the power dissipated by each resistor. What is the net power dissipated by all the resistors? g) If you did the calculations correctly, then the answer for the net power being converted to heat in the resistors should be equal to the square of the net current out of the battery times the net resistance of the resistors. If it is not, rework the problem until it does.

Answer 1

The current voltage and power in circuit
