Complete The Circuit
This is the name of the pathway that must exist for electric current to flow, requiring no gaps or breaks between the power source and components.
What is a closed circuit?
This is the mathematical formula that expresses Ohm's Law, relating voltage, current and resistance.
What is V = IR?
This is the formula used to calculate electrical power, expressed in terms of voltage and current.
What is P = VI?
This is the name of the component represented in a circuit diagram by a long line and a short line side by side, used as the source of electrical energy.
What is a battery (or cell)?
This is the name of the type of circuit in which all components are connected in a single loop, meaning the same current flows through every component.
What is a series circuit?
This is the name of the unit used to measure electric current, and the instrument used to measure it in a circuit.
What is the Ampere (amp), measured with an ammeter?
This is the value of the current flowing through a resistor with a resistance of 10 ohms connected to a 20 volt power supply.
What is 2 amps?
This is the name of the unit of electrical energy commonly used by power companies to measure household electricity consumption.
What is the kilowatt-hour (kWh)?
This is the name of the component represented by a zigzag line in a circuit diagram, used to oppose the flow of current.
What is a resistor?
This is the name of the rule stating that the total current entering a junction in a parallel circuit equals the total current leaving it, and the broader physical principle it is derived from.
What is Kirchhoff's Current Law
This is the reason why an ammeter must always be connected in series rather than in parallel when measuring current in a circuit.
What is none to little resistance?
This is the name given to a graph of voltage versus current for an ohmic conductor.
What is a linear?
This is the term for the rate at which electrical energy is converted to other forms, and the specific difference between this quantity and energy itself in terms of units.
What is power or what is watts?
This is the name of the component that allows current to flow in only one direction.
What is a diode?
This is the name of the configuration used in most residential wiring where each room or appliance is on its own branch.
What is parallel wiring?
This is the name of the effect that causes electrons in a conductor to be pushed to the outer surface when carrying high frequency alternating current, reducing the effective cross sectional area and increasing resistance.
What is the Skin Effect?
This is the full name of the German physicist who formulated Ohm's Law in 1827
Who is Georg Simon Ohm?
This is the name of the effect that describes how electrical energy is converted to heat as current flows through a resistor
What is the Joule Heating Effect?
This is the name of the component used in circuits to store electrical charge temporarily, represented by two parallel lines of equal length in a circuit diagram
What is a capacitor?
This is the circuit configuration that Taylor Swift's lighting rig crew would need to avoid at all costs when designing a stadium concert setup, because a single blown globe would black out the entire stage.
What is a series circuit?
This is the name of the Danish physicist who first demonstrated the relationship between electricity and magnetism in 1820 by observing that a compass needle deflected when placed near a current carrying wire.
Who is Hans Christian Ørsted?
This is the name of the law that relates the voltage around any closed loop in a circuit to the sum of the voltage drops across each component.
What is Kirchhoff's Voltage Law?
This is the full name of the Scottish engineer who defined the unit of power now named after him.
Who is James Watt?
This is the name of the circuit component whose resistance decreases as light intensity increases.
What is a Light Dependent Resistor (LDR)
This is the name of the theorem used to simplify complex circuits that cannot be reduced by simple series and parallel rules alone, which states that any linear circuit can be replaced by a single voltage source and series resistor from the perspective of a load.
What is Thévenin's Theorem?
