What is the voltage drop across each resistor in the circuit shown here? 1Ω 2Ω 3Ω 12V

4V, 6V, 2V Solution: 3Ω + 2Ω + 1Ω = 6Ω 12V / 6Ω = 2A 2Ω * 2A = 4V 3Ω * 2A = 6V 1Ω * 2A = 2V

If you have two 3000 ohm resistors in series, what is the total resistance?

6 kΩ Solution: 3 kΩ + 3 kΩ = 6 kΩ

Given a series circuit containing resistors of different values, which statement is not true?

The voltage drop across each resistor is the same.

How much current flows in a circuit with a 1.5-volt battery and three 1 ohm resistances (bulbs) in series?

0.5 A Solution: 1Ω + 1Ω + 1Ω = 3Ω 1.5V / 3Ω = 0.5A

How much current flows in a circuit with a 18-volt battery and six 1 ohm resistors (bulbs) in series?

3 A Solution: 1Ω + 1Ω + 1Ω + 1Ω + 1Ω + 1Ω = 6Ω 18V / 6Ω = 3A

If 5 V and 16 V power supplies are connected in series-opposing, what is the total voltage?

11V Solution: 16V - 5V = 11V

What is the current flowing in the circuit shown here? 1Ω 2Ω 3Ω 12V

2 A Solution: 3Ω + 2Ω + 1Ω = 6Ω 12V / 6Ω = 2A

In a series connected circuit with 100 Christmas bulbs, if one bulb burns out what happens to the remaining bulbs?

All bulbs turn off

Voltage sources cannot be added in series if they equal values and same polarities.

False

An ammeter is always connected in ______________ with the other components in an electrical circuit.
