I have to draw a schematic diagram of my kitchen. I have been asked to draw a circuit I need to include my tv, light bulbs, dishwasher etc how would I represent these? Or do I not include them at all? Would I represent these items as resistors?

a) What does the voltmeter show in the schematic? b) what does the ammeter show in the schematic? c) how much power is developed in the resistor R5? d) What is the replacement resistor for the entire circuit (disregarding internal resistances of the source and instrument?

We know a voltmeter must be connected in parallel, but what does that imply about its internal resistance? Is it really big, or really small? If the voltmeter is connected in series (don't do that!), how does it affect the circuit? Include a sketch to illustrate your reasoning.

In the following circuit, lo = 0.171 A, I, = 0.043 A, and I2 = 0.129 A. Find the potential difference from A to B going along the following paths (show all work): a) Through the battery and the 20 Q resistor on the bottom. b) Through the resistors in the middle (40 Q and 20 Q). c) Through the 20 Q resistor on the far right.

Hi! I've submitted this question a few times, and I keep getting a different answer, so I just want to see one more person's perspective. Thank you!

This homework problem is giving me some issues, help would be greatly appreciated! Thanks!

I don't understand

I need help finding the voltage across the 1500 ohm resistor and the current through the 3900 ohm resistor.  Attached is a picture of the circuit.

14. (C2, 4, 31, 32, 38) Rank the following quantities (ie tell me which is larger or if they are equal,) for the circuit to the right. Explain your reasoning. The wires have resistivity PB-5PA, length LB-2LA, and radius RB=3RA. The current density though wires A and B The resistance of wires A and B 6V
