7.
What is the total voltage of the circuit in figure 3?​

Answer 1

Answer:

1. 3

2.3

3.1

4. 1

5. 1.5 volts

6. 3 volts

7. 4.5 volts

Answer 2

1. Light is brightest in the the third configuration since there is a greater quantity of voltage supply.

2. The third configuration supplies the greatest amount of current, since the quantity of voltage supply is greatest.

3. The first configuration is dimmest due to having the least voltage supply.

4. The first configuration has the least amount of current due to having the least amount of voltage supply.

Having V = 1.5V

Total voltage in a series circuit = sum of individual voltage drops

5. Total voltage = 1.5V

6. Total voltage = 1.5 + 1.5

                          = 3V

7. Total voltage = 1.5 + 1.5 + 1.5

                          = 4.5V
