Electronics Worksheet: Voltage, Current and Resistance

Electronics lesson 11: Voltage, current and resistance · Set 133 · 40 questions

Remember (Push, flow, resist): Voltage → volts (V), current → amperes (A), resistance → ohms (Ω), power → watts (W). milli (m) = ÷ 1000 and kilo (k) = × 1000: 250 mA = 0.25 A, 2.2 kΩ = 2200 Ω. Voltmeter across a part; ammeter in series.
