This law governs the potentials which are observed in nerve cells with electrodes. We will first demonstrate Ohm’s Law and its application in biological materials. 1.3) Materials Item Quantity Breadboard 1 Resistors : 330 K 1 Ω : 100 K 12 Ω : 33 K 6 Ω : 22 K 1 Ω : 10 K 6 Ω : 4.7 K 1 Ω : 2.2 K 1 Ω : 1.5 K 1 Ω : 1 K 1 Ω : 510 1 Ω : 330 1 Ω : 220 1 Ω : 150 1 Ω : 100 1 Ω Capacitors : 0.10 µF 6 : 10.0 µF 6 Wires 12 PowerLab 1 PowerLab Output Leads 1 PowerLab Leads 1 Voltmeter (Current Capable) 1 Resistor Coding Key Color Digit 1st Band 1st Digit – Black 0 2nd Band 2nd – Brown 1 Red 2 3rd Band Number of Zeros – Orange 3 Yellow 4 4th Band Tolerance – 5 Blue 6 Violet 7 Grey 8 White 9 Silver 10% Tolerance Gold 5% Tolerance
