What is a series circuit?
Series means all the components are connected end-to-end or one after another.
100
Define Voltage and what unit does it use?
Voltage, in simplest terms, is linked to the electrical energy within a connected circuit; the unit that is used to measure it is Volts (with its symbol being V)

What is a parallel circuit?
In a parallel circuit, there is more than one path for the current to flow. The paths where current can flow are branches. It is called parallel since the branches are drawn in parallel lines.

what is current, and how to measure it?
Electric current refers to the flow of electricity in an electronic circuit, and to the amount of electricity flowing through a circuit
200
Define Resistance and what unit does it use ?
The measure of how easy or hard it is for electrons to flow through a material.
Resistance is measured in the unit Ohms (Ω)
300
The rule for parallel circuits?
The current through the cell is equal to the total of the current in all the branches.

How to measure the volts, and what is the rule of the device?
Voltage is measured using a voltmeter.
Voltmeters are connected in PARALLEL with the component.

Explain Ohm's law
- Ohm’s law is an equation that connects together Voltage, Current, and Resistance
The equation is V = IR
- V being voltage, I being current, and R being resistance.

Advantages of Parallel circuits?
The current through a branch can keep flowing even if the current stops flowing in the other branches
Different components can be switched on and off independently.
If one component in the circuit stops working, the other branches are not affected.

difference between how volts work in a series circuit when compared to a parallel circuit
In a series circuit the voltage is addition of all the voltage elements. In a parallel circuit the voltage is the same for all elements.
