ri R$ 7:) Here, each V represents a change in voltage (in volts) at a battery, each R represents a resistance (in ohms) at a resistor and each I represents a current (in amps) through a wire. These quantities obey two simple laws: 1. Ohm's law: The voltage drop across a resistor is V = IR. 2. Kirchhoff's second law: The sum of all the voltage changes in a closed loop is zero. Using these two laws, we can construct...

2. Design an approximate voltage source from a current source and a resistor in parallel with it. The open circuit voltage should be 5.0 volts, and it should drop to no lower than 4.9 volts when a 100 Ω load is attached. What is the short-circuit current IN and parallel resistance RN?

I understand all the concepts of what voltage is using all the analogies but some things related to the drop of voltage across a circuit confuses me. If I had a short circuit and attached a voltmeter I would get a potential difference reading of 0 volts. How is current then going through the wire if it is 'X' volts at any point in the wire? Let's say I have a DC 9V battery with a load in the middle....

You have a 20 V voltage source and need to “plug in” 3 appliances. The appliances have resistances of 4 ohms, 2 ohms and 2 ohms respectively. The 4 ohm appliance requires a current of 4 A and the 2 ohm appliances each require a current of 2 A. Show the necessary configuration to make this possible. How much energy would the 2 ohm appliance dissipate in 40 s? How many electrons pass through the 4 ohm resistor each second?
