Battery Safety: 6.0 V only; leads should be unattached to breadboard when not in use; leads should never be connected to each other. unattached 6 V only Resistor Safety: Caution: resistors can get hot with use; disconnect and allow to air-cool. LED Safety: Always use a 100-ohm resistor in series with any LED resistor & LED leads twisted together for a series circuit Blue (or green) 100 Q LED Resistor 1 HP 910 BT Keyboard connectedCircuit #1 Front of Breadboard: The 'holes' in the breadboard have tiny metal clasps to grab & hold wires placed in the holes. + Back of Breadboard (covering removed to expose metal 'wiring'): Note the long, separated metal strips on the top and bottom and the short metal strips in between. *Some photos show a 4.5 V battery pack. Pretend it is your 6.0 V battery pack and continue on.* Some photos show a 4.5 V battery pack. Pretend it is your 6.0 V battery pack and continue on. 1. Measure the voltage rise of the battery pack. sample: 9.00 V BTMETER Voltmeter (turn dial to blue V) Voltmeter leads [ connect to battery lead) Voltmeter leads (connect to battery lead) DC Battery Your answer2.
