Chapter 3: Running Around in Circuits First, measure the voltage supplied to the circuit by the battery pack. Connect the positive (red) multimeter lead to the point where the positive (red lead) side of the battery pack connects to the resistor, and the negative (black) multimeter lead to the point where the negative (black lead) side of the battery pack connects to the LED. See Figure 3-10. Do you get a voltage reading that is close to the nominal supply voltage of 6 V? ) Figure 3-10: Measure the voltage supplied by the battery pack.

5 volts — regardless of size. The difference in size among those batteries has to do with how much current can be drawn from them. The larger the battery, the more current can be drawn, and the longer it will last. Larger batteries can handle heavier loads, which is just a way of saying they can produce more power (remember, power = voltage × current), so they can do more work.

99, but you can find larger quantities for less money online. •• Condenser microphone (optional). 99) or similar. •• One wooden pencil or small‐diameter wooden dowel. •• One relatively strong bar magnet, approximately 2 inches long. Getting Ready to Rumble After you’ve purchased all your supplies, tools, and components, you need to do a few things before you can start building circuits: ✓✓ Attach a battery clip to a 9‐volt battery. The clip provides leads so you can connect the 9‐volt battery to your solderless breadboard.
