Answer 2

Source voltage

Question 3

If the resistance and voltage are known what is the formula for finding the current (amps)?

Answer 3

I=E/R

Question 4

A series circuit has three resistors of 4 ohms each. The voltage drop across each resistor is 4 Volts. Technician A says that the source voltage is 12 Volts. Technician B says that the total resistance is 18 ohms. Which technician is correct?

Answer 4

Technician A

Question 5

If a 12 V battery is connected to a series circuit with 3 resisters of, 2 ohms, 4 ohms, and 6 ohms, how much current will flow through the circuit?

Answer 5

1 amp

Question 6

A series circuit has two 10-ohm bulbs. A third 10-ohm bulb is added in series. Technician A says that the three bulbs will be dimmer than when only two bulbs where in the circuit. Technician B says that the current will increase. Which technician is correct?

Answer 6

Technician A

Question 7

Technician A says that the sum of the voltage drops in a series circuit should equal the source voltage. Technician B says that the current varies depending on the value of the resistance in a series circuit. Which technician is correct?

Answer 7

Technician A

Question 8

Two lightbulbs are wired in series and one bulb burns out. Technician A says that the other bulb will work. Technician B says that the current will increase and the circuit because one electrical load is no longer operating. Which technician is correct?

Answer 8

Neither

Question 9

Four resisters are connected to a 12 V battery source in series. The values of the resistors are 10 ohms, 100 ohms, 330 ohms, and 470 ohms. Technician A says that the greatest voltage drop will occur across the 10 ohm resistor. Technician B says that the greatest voltage drop will occur across the 470 ohm resistor. Which technician is correct?

Answer 9

Tech B

Question 10

Three lightbulbs are wired in series. A fourth bulb is connected to the circuit in series. Technician A says that the total voltage drop will increase. Technician B says that the current (amps) will decrease. Which technician is correct?

Answer 10

Technician B
