Exercise # 1 1) What is the voltage at site 1? V volts What is the voltage at site 2? 0 volts What is the current at site 1? V/R amps What is the current at site 2? V/R amps All the voltage is “dropped” across the resistor. Current only splits in parallel so in this case, it is the same current that flows at sites 1 and 2. 2) What is the voltage at site 1? V volts What is the voltage at site 2? V volts How much current flows down the R1 resistor? V/R 1 amps How much current flows down the R2 resistor? V/R 2 amps How much current flows at site 1? V R 1 + V R 2 = V g 1 + g 2 ( ) = V R 1 + R 2 R 1 R 2 ( ) Voltage is constant in parallel, so it is the same at sites 1 and 2. Then you can calculate the individual currents that flow down each resistor from Ohm’s law. At any one point, the current flow in must equal the current flow out. So the current at site 1 must equal the sum of the currents that flow down the two resistors. R
