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...
