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
