Select Resistors Find the 220 and the 470 resistors from your Boe-Bot kit. Example: 470 resistor: 4 = yellow 7 = violet Add 1 zero to 47 to make 470, so 1 = brown Now, find the 220 resistor. So, 470 = yellow , violet , brown
I Build the Parallel Circuit Below (measure the total current from the power source) Vin=6V 470 220 + - - - current measurement Compute the current after you make your measurement. How close are the measured and computed results? current flow

Unformatted text preview: +---current measurement current flow Modify the Parallel Circuit as Shown (measure the current through the 470 resistor) Compute the current after you make your measurement. How close are the measured and computed results? current flow Vin=6V 470 220 +---current measurement Check for Conservation of Charge ~ ~ Kirchoffs Current Law (KCL) The algebraic sum of currents entering a node is zero. Current In = Current Out Vin=6V 470 220 +---I = I = more current goes through smaller resistor Electrons are like people they follow the path of least resistance. The End...
