## What is the main problem with series circuits?

A disadvantage of series circuits is that if there is a break or fault at any of the appliances connected to the circuit, the remaining appliances will be cut from the supply. Regarding parallel circuits, appliances can be connected and disconnected to the circuit without affecting other parts of it.

### How can we investigate current in a series circuit?

Method 3 – Current measurements

1. Set up the series circuit with 2 bulbs.
2. Connect an ammeter in each of the 3 positions shown in turn.
3. Record all of your measurements.
4. Set up the parallel circuit with 2 bulbs.
5. Connect an ammeter in each of the positions shown in turn.
6. Record all of your measurements.

#### What are the examples of series circuits?

An example of a series circuit is a string of Christmas lights. If any one of the bulbs is missing or burned out, no current will flow and none of the lights will go on. Parallel circuits are like the smaller blood vessels that branch off from an artery and then connect to a vein to return blood to the heart.

What will happen if we decrease the number of bulb in a series circuit?

Placing cells in series increases the voltage in the circuit by 1.5 V for each cell. Increasing the number of bulbs in a series circuit decreases the brightness of the bulbs.

What are the applications of series circuit?

Automatic house- heating equipment has a thermostat, and safety cut-out connected in series with a voltage source. Water heaters, well water pump, lamps, freezers and refrigerators are some of the other appliances which use a series circuit.

## How to design a series and parallel circuit?

Design any tables you will need to make sure your data collection is able to be clearly communicated to others before you commence your experiment. To examine the voltage and current flow in a series and parallel circuit of resistors. To examine the voltage and current flow in a series and parallel circuit of resistors.

### How to examine series and parallel circuit of resistors?

To examine the voltage and current flow in a series and parallel circuit of resistors. To examine the voltage and current flow in a series and parallel circuit of resistors. Attach the components together in a circuit as shown in the following diagram.

#### How to calculate the resistance of a series circuit?

1 Components in a series circuit share the same current: I Total = I 1 = I 2 = . . . I n 2 The total resistance in a series circuit is equal to the sum of the individual resistances: RTotal = R 1 + R 2 + . . . R n 3 Total voltage in a series circuit is equal to the sum of the individual voltage drops E Total = E 1 + E 2 + . . . En

Why is the amount of current in a series circuit the same?

The amount of current in a series circuit is the same through any component in the circuit. This is because there is only one path for current flow in a series circuit.
