Ch 5 - Series Circuits

The amperage in a series circuit is ______________.

The same anywhere in the circuit.

The sum of the voltage drops in a series circuit equals the ______.

Source Voltage

If the resistance and the voltage are known, what is the formula for finding the current?

I = E / R

A series circuit has three resistors of 6 ohms each. The voltage drop across each resistor is 4 volts. Tech A says that the source voltage is 12 volts. Tech B says that the total resistance is 18 ohms. Which tech s correct.

Both

If a 12 volt battery is connected to a series circuit with three resistors o 2 ohms, 4 ohms, and 6 ohms, how much current will flow through the circuit?

1 amp

A series circuit has two 10 ohm bulbs. A third 10 ohm bulb is added in series. Tech A says that the tree bulbs will be dimmer than when only two bulbs were in the circuit. Tech B says the current in the circuit will increase. Which tech is correct?

Tech A

Tech A says that the sum of the voltage drops in a series circuit should equal source voltage. Tech B says that the current (amperes) varies depending on the value of the resistance in a series circuit. Which tech is correct?

Both Techs

Two light bulbs are wired in series and one bulb burns out (opens). Tech A says that the other bulb will work. Tech B says that the current will increase in the circuit because one electrical load (resistance) is no longer operating. Which tech is correct?

Neither

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

Tech B

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

Tech B
