Which of the following statements is true about electric circuits? • in a series circuit, the voltage at the source is the same as the voltage measured at each load in the circuit

• when 2 dry cells are connected in series, the positive electrode of one cell is connected to the positive electrode of the other

• electrons leave the source at the positive electrode

• lights in the home are connected in series

• in a parallel circuit the current value from the source is equal to the sum of the current values in each branch of the circuit

Explanation:

E: True. The last one is the true statement.

D: False: If home lights were connected in series, when you turned one of them off, they all would go off.

C: The opposite is true. Electrons flow towards the positive pole of a battery. Just as with people, opposites attract.

B: False. What is being described is a parallel circuit. In a series circuit. the positive pole of one battery is connected to the negative pole of the next battery. The other end of each battery is connected to the load.

A: False. There is a voltage drop on each load in series. These drops add together to equal the source voltage.
