Why electrical appliances are not connected in series?
Answer. Electrical appliances are not connected in series because current will be same through all the appliances connected whereas appliances have different current ratings and also that voltage decreases as more no. Of appliances are connected.
What happens if the household electric appliances are connected in series?
Also, if the appliances were wired in series, the potential difference across each appliance would vary depending on the resistance of the appliance. This would make it very difficult to provide the right power to flow through the appliances.
In what way household appliances should be connected?
Answer. They are connected in parallel. The reason for the parallel connection is that it results in each appliance operating at the same voltage (i.e., approximately 120V for line-neutral connected appliances, and 240V for appliances that are connected line-line) along the entire circuit.
Why domestic electrical appliances are earthed?
Electrical appliances are earthed to protect from an electric shock. Due to break of insulation of wire, live wire may come in contact with the body of the appliance and pass the current to the appliance and on being touched a fatal shock can occur.
Are appliances connected in series?
Household appliances aren’t connected in series because if they were they would have to “share” the line voltage with the other appliances in the circuit. Each time an appliance was added to the circuit, the voltage available to run each appliance would go down, along with the current through each appliance.
How are electric appliances connected in house in series or parallel and write one advantage of such connection?
Two advantages (i) To have equal potential difference across each appliance. (ii) Each appliance has separate switch to the flow of current through it, so that each circuit can work independently.
What safety measures must be taken while working with electrical appliances?
15 Safety Precautions When Working With Electricity
- Avoid water at all times when working with electricity.
- Never use equipment with frayed cords, damaged insulation or broken plugs.
- If you are working on any receptacle at your home then always turn off the mains.
- Always use insulated tools while working.
