QUESTIONS LIST:
- electric current : this is defined as the amount of charge passing a point in a conductor every second.
- ohms law : this is the relationship between voltage, current and resistance, which is usually written as a formula: v = ir.
- total : in a series circuit, the sum of the voltages lost on the loads equals the _ voltage supplied by the battery.
- mega : this prefix represents one million.
- resistor : this is an electrical component that has a specific resistance and are marked with coloured bands.
- parallel : when a load is placed in _ with another load, another pathway is created so the total resistance must decrease.
- decrease : since loads placed in series increase the total resistance of the circuit, they _ the total current throughout the circuit.
- load : this causes resistance by hindering the flow of electrons.
- ohm : this is the unit used to measure resistance.
- series circuit : this is a circuit that has only one path for the current (electrons) to travel.
- battery : in an electrical circuit, this is similar to a pump; it raises charges to a higher level of electrical potential energy.
- current : resistance is inversely proportional to this.
- high : a light bulb filament has this kind of resistance.
- voltage : current is directly proportional to this.
- kilo : this prefix represents one thousand.
- parallel circuit : this is a circuit that has several different paths for the current (electrons) to travel.
- milli : this prefix represents one-thousandth.
- switch : this is like a valve that determines whether electrons are allowed to flow through the circuit or not.
- sum : the total current entering a junction point must equal the _ of the current leaving the junction point.
- equal : since there is only one path for the electrons to travel in the series circuit, the current in each part of the circuit is this.
- junction point : the location where a circuit divides into multiple paths or where multiple paths combine is called this.
- current electricity : this is the continuous flow of charge through a complete (closed) circuit.
- resistance : this is the property of any material that slows down the flow of electrons and converts electrical energy into other forms of energy.
- same : loads that are in parallel have the _ voltage as each other.
- wires : these have very little resistance.
