Answers
a) define an electric circuit.
An electric circuit is a path in which electron flow from a voltage or current source flow.
b)Name and draw the two type of circuit.
There are 2 type of circuit:
- series
- parallel
learn about electric circuit.
Electric Circuit
The electric circuits are closed-loop or path which forms a network of electrical components, where electrons are able to flow. This path is made using electrical wires and is powered by a source, like a battery. The start of the point from where the electrons start flowing is called the source whereas the point where electrons leave the electrical circuit is called the return.
Let’s conduct a small experiment, you would need the following:
Electric bulb
Wire
Electrical tape
A battery
Electric Circuit
Connect the wires to the bulb and connect one end of the wire to the battery, notice what happens, there won’t be any change in the bulb, but when you connect the free wire to the battery and complete the circuit, you will notice that the bulb starts glowing, therefore the circuit must be completed in order for the current to flow.
An electrical circuit complete only when there is at least one closed loop from positive to the negative end. This is the simplest form of an electric circuit, the circuit found inside a television is more complicated and has different components.
Electric Circuit
You might have seen these danger signs on electric poles, transformers and sometimes even on some electrical equipment at home, it is to warn you about the dangers of electricity, and electricity, if not handled properly, could be lethal and can even cause deaths. Electric wires sockets and live wire should be properly insulated and kept away from the reach of children, the voltage in a small battery does not exceed more than 12 volts but the voltage in a transformer may reach up to 11000 volts.
Electric Circuit
Simple Circuit
A simple circuit comprises the power source, conductors, switch, and load.
