Electricity Refresher Crossword Puzzle

QUESTIONS LIST:

• current : rate of flow of charge in a circuit
• voltage : energy per unit of charge passed
• resistor : component that limits the flow of current
• circuit : complete path that electricity can flow around
• battery : provides energy to the circuit
• cell : single source of voltage in a circuit
• wire : carries current between components
• switch : can open or close a circuit to stop or allow current
• lamp : lights up when current passes through it
• series : circuit with components in one path
• parallel : circuit with branches so current can split
• diode : component that only lets current flow one way
• straight : the shape of the i–v graph for a resistor that behaves the same as voltage changes
• nonlinear : component with a curved i–v graph, like a lamp or diode
• gradient : the slope of an i–v graph showing resistance
