Your assignment is to prepare and submit a paper on engineering science. Hence for the three resistors in parallel, the effective resistance Rf = 1/7+1/12+1/14= 50/1 68. Flipping this upside down gives 168/50Ω

For the second set of resistors in parallel, their equivalent resistance Rf = 1/16+1/19= 35/304, and flipping this upside down yield 304/35 Ω. The total circuit resistance is found by summing the 304/35 Ω and 168/50Ω. This amounts to 12.0446 Ω.

d) The Pd across each of the two resistors in parallel in parallel is found by subtracting 6.69446V from 24V. This equals to 17.306V. Therefore, using ohms laws, the amount of current through the 19 Ω resistor is V/R= 17.
