The Electric Current and Cells: Cells in a Parallel Circuit

The video tutorial explains the concept of potential difference in parallel circuits. It begins by describing a single cell circuit with a 1.5V battery and a bulb, showing how the voltmeter reads 1.5 volts. It then explores a circuit with three 1.5V cells connected in parallel, demonstrating that the total potential difference remains 1.5 volts. The tutorial highlights the advantage of increased available power when cells are connected in parallel.

What is the potential difference produced by a typical cell?

• 3 volts

• 1.5 volts

• 2 volts

• 0.5 volts

When a single 1.5 Volt battery is connected to a bulb and a voltmeter, what reading does the voltmeter display?

• 3 volts

• 1.5 volts

• 2 volts

• 0 volts

How are the positive terminals of batteries connected in a parallel circuit?

• Not connected at all

• With separate wires for each battery

• Joined together with a single wire

• In series with the negative terminals

What is the total potential difference in a circuit with three 1.5 Volt cells connected in parallel?

• 1.5 volts

• 3 volts

• 0 volts

• 4.5 volts

What is the main advantage of connecting batteries in parallel?

• Decreased resistance

• Increased available power

• Increased current

• Increased voltage
