Exit tickets - Electric circuits

What type of circuit is this?

• Simple

• Parallel

• Series

• Complex

Answer explanation

The circuit only has one conductive pathway for the electric current to flow and therefore must be a 'series' circuit - the most simple of all the circuits

I can identify the type of circuit - series or parallel

What is the value of voltage shown on the voltmeter?

• 3V

• 6V

• 12V

• 2V

Answer explanation

In series circuits the voltage is shared among the components. In the event that the components are exactly the same, the voltage from the battery is shared evenly. In this case there are 6V of voltage (push) from the battery and this means 3V will be 'dropped' at each bulb.

I can identify the voltage across components in series

Answer explanation

The voltage on the bulb is 3V and the current flowing through it is 2A...3/2 = 1.5 ohms

I can use ohms law to calculate V, I and R

What value would be on the voltmeter is the battery provides 6V of voltage to the parallel circuit?

• 12V

• 6V

• 3V

• 2134V

Answer explanation

In parallel circuits each conductive pathway receives the total voltage from the battery. In this case there is only one bulb on each path so each bulb receives 6V.

I can identify the voltage across the components in a parallel circuit

If there is 2A of total current flowing from the battery, what value of current will flow through the ammeter?

• 3A

• 2A

• 1A

• 4A

Answer explanation

In parallel circuts the current divides among the conductive pathways. If the conductive pathways have the same resistance the the current splits evenly. If not, electrons will always take the path of least resistance and so more current will flow through the path that has less resistance.
