I'm studying for an exam coming up soon. I don't want the answer, I want the formula for solving this problem or some insight into how to solve this problem. I'm gonna post a file with this, with the circuit. Thank you for the help, I will appreciate any and all.
With switch S1 closed, you disconnect jumper wire J2.
Then, you connect your meter between points C and D and measure the current in the circuit. What current
reading will your meter display?
A. 1 A C. 1,000 mA
B. 0.5 A D. 30 mA
The ammeter is usually considered a direct short for circuit problems like this one, so you just have to know how to combine parallel and series resistances and also how current divides in a parallel circuit. If you think about that you can probably come up with the answer to this.
After doing the steps from JimB, try also searching for current divider formula. It might help you finish a given problem faster. But you'll have to master simplifying resistances connected in series or in parallel, or series-parallel resistances.
Ok guys thank you. I'm good with the rest of the questions, thanks for all the help. I appreciate it very much. Test is next week, let you know what I get.
