Current in a series circuit

Current is the same wherever you measure it.

<p>Current is the same wherever you measure it.</p>
2
New cards

Series circuit: If any of the parts are broken...

The circuit is incomplete, and no current will flow.

3
New cards

Voltage in a series circuit

Voltage across each component adds up to the voltage across the cells.

<p>Voltage across each component adds up to the voltage across the cells.</p>
4
New cards

Voltage in a parallel circuit

Voltage stays the same in each branch of the circuit.
- Voltage across each branch is equal to the voltage across the cells.

<p>Voltage stays the same in each branch of the circuit. <br>- Voltage across each branch is equal to the voltage across the cells.</p>
5
New cards

State the law of current

The sum of the currents flowing into a junction equals the sum of the currents flowing out of a junction.

6
New cards

State the law of voltage

The sum of the voltages across each component, on the same branch, is equal to the battery voltage.

7
New cards

Series circuit: The more components you add in series...

The LOWER the current.

New cards

Current in a parallel circuit

Current is shared between branches.
- The current in each branch adds up to the total current in the circuit.

<p>Current is shared between branches. <br>- The current in each branch adds up to the total current in the circuit.</p>
