Question

Three resistors A, B and C are connected in parallel and take a total current of 7.9 amp. Resistor A takes 2.5 amp and has a resistance of 48 ohms; also, the current through B is twice as much as that through C. Calculate a) IB and IC, b) the line voltage, RB and RC.

Step 1

So, we have: 7.9 amp = 2.5 amp (through A) + IB (current through B) + IC (current through C) Given that the current through B is twice as much as that through C (IB = 2IC), we can substitute this into the equation: 7.9 amp = 2.5 amp + 2IC + IC Solving for IC, Show more…
