After this lesson, you should be able to:

• Connect cells in parallel and know how this connection affects the total voltage and current in the circuit
• Describe the characteristics of a parallel connection of devices
• Determine the value of a resistor from its colour coding
• Explain how parallel connections of identical resistors or other devices affect the

• total current in the circuit
• the current in each additional resistor
• the potential difference across each resistor
• the potential difference across all resistors

• Explain why electrical connections at home are in parallel
