E.2.0 Units of measurement in electrics E.2.6 Measuring electrical voltage An electrical voltage is measured with a voltmeter. Modern digital multimeters allow various measuring ranges to be set. To measure the voltage, the measuring instrument is connected to the consumer in parallel. U R R (resistance) represents a consumer Connect measuring instrument (voltmeter) in parallel Note the setting - For AC = V~ - For DC = V- Note the connections (no difference between AC and DC)
E.2.0 Units of measurement in electrics E.2.7 Electrical resistance Electrical resistance (symbol: R) is an electrical engineering term. It is a measure of how much voltage is necessary for a specific current to flow through an electrical conductor. The electrical resistance is generally temperature dependent. The specific resistance of a conductor is equal to its resistance at a length of 1 m, a cross-section of 1 mm² and a temperature of 20°C. The symbol for electrical resistance is R. This stems form the English word „resistance“ or „resistor“. Units of measurement: MOhm (megaohm), kOhm (kiloohm), Ohm, mOhm (milliohm) The ohm (Ω) (large Omega symbol) is the basic SI unit (SI = International System of Units). Every consumer, e.g. electric light bulb or heating rod, can be regarded as a resistor. The system must be voltage-free to measure resistance!
