In this first experiment, you connect two AA batteries in a series circuit. The positive terminal of a battery is connected to the negative terminal of the second battery. Both batteries have a voltage of 1.5 V. What is the resulting voltage?
To find out, construct the shown circuit and measure the voltage.

You measure a total voltage of 3 V. In a series circuit of batteries the voltages of the individual batteries add up... Utotal = U1 + U2 = 1.5 V + 1.5 V = 3.0 V |
