Drawing Series Circuits

Today we will be drawing circuits for simple series circuits.

Multiple Choice

As the resistance of a circuit increases, the current of the circuit.

When thinking of a circuit will more resistance allow a current to flow easier or more difficult?

• increases

• decreases

• stays the same

Circuits

• Electric Circuit: a path in which electrons from a source of potential difference (voltage) flow.

• Series Circuit: a closed electric circuit in which the current flows through only one path.

Sample Question #1

• A circuit contains a 5 ohm resistor, a 10 ohm resistor and an unknown resistor are connected in series to a 9V.

• An ammeter (voltmeter) is reading the entire circuit.

Sample Question #2

• A 6 ohm resistor and an unknown resistor are connected in series to a 12 V batter. An ammeter is reading only the current of the unknown resistor.

Multiple Choice

A 6 ohm resistor and a 5 ohm resistor are connected in series to a 9 V battery. A voltmeter is placed to read the potential difference of the whole circuit.

What is the symbol used for each resistor?
