Hey! Happy new year.
We’re back at work and happy to help you with any of your electrical requirements. But in case you’re still in holiday mode, we’d like to entertain you with a few fun electricity facts, how to charge your electric car at home (if you have one) and a simple explanation on the difference between AC and DC power.

Thinking of buying an electric car?
We can help you charge it at home.
Electric cars aren’t a common sight around Sydney yet, but their popularity is growing. Two of the challenges of owning an electric vehicle is the lack of public charging stations and the time they take to recharge.
We are solving these problems for our clients with electric cars by installing car chargers in their homes. To reduce the costs of recharging your electric car, pre-set the charger for off-peak rates if your electricity provider offers time-of-use tariffs.
If you have solar panels, we suggest you install a battery back-up so you are always charging your electric car for free.
Just one thing to note with solar panels – they generate DC (or direct current) power so you need to ensure you install a DC to AC inverter. But don’t worry. We can take care of everything for you.
What’s the difference between DC and AC power?
Electricity is the movement of electrons across a wire or other conductor.
DC = Direct Current. It means the electrons move in one direction only. Batteries all use DC power (including your mobile phone battery) but your power supply is AC. In the case of your phone recharger, it converts the AC power coming out of your powerpoint into DC power.
AC = Alternating Current. It means the electrons move backwards and forwards. In Australia, they change direction every 50 seconds. AC power is better for long-range transmission than DC power because it can be sent through wires at enormous voltages with a minimal loss of power. That’s why it’s used in our cities.
So now you know the difference between AC and DC power and why you need more than a simple powerpoint to charge your electric car.
Return to work with 5 electrifying facts to spark workplace conversations
While we’re explaining the nuts and bolts of electricity, here are 5 more electric facts to spark conversation at work.
Fun Electricity Fact 1 – Electricity wasn’t invented. It was discovered. Ugh? An invention is something humans produce that doesn’t exist in nature. Electricity is a naturally occurring form of energy. That makes it a discovery.
Fun Electricity Fact 2 – The Ancient Greeks discovered static electricity by observing what happened when they rubbed amber and fur together. In case you’re wondering what happens, they attract each other.
Fun Electricity Fact 3 – The Ancient Romans and Persians both developed primitive batteries by wrapping pots with copper sheets. Scientists believe these early batteries were used for electroplating. Electroplated artefacts from antient times can be found in museums across the world.
Fun Electricity Fact 4 – In 1800 an Italian scientist named Alessandro Volta built the first electric battery that could produce a steady stream of electrical charge (or voltage).
Fun Electricity Fact 5 – In 1831, Michael Faraday worked out how to generate electrical current steadily and practically by using a copper wire coil and a magnet.

We have 4 key service promises. Here’s one of them – We’re problem solvers.
We will happily do the electrical work for new builds and renovations. But when it comes to adding or changing light fittings, powerpoints or switches to existing homes, it can get a little tricky. But we love the challenge of finding innovative ways to achieve what you want and make it look great.
So next time a friend or family member is talking about getting some electrical work done, please tell them about us.
