Name Purpose Ammeter (Ampermeter) Measures current Capacitance meter: Measures the capacitance component Current clamp: Measures current without physical connection Curve tracer: Applies swept signals to a device and allows display of the response Cos Phi Meter: Measures the power factor Distortionmeter: Measures the distortion added to a circuit
Electricity can be given a quality — a potential. And electricity has a substance-like property, the electric charge. Energy (or power) in elementary electrodynamics is calculated by multiplying the potential by the amount of charge (or current) found at that potential: potential times charge (or current).
Electrical measurements are the methods, devices and calculations used to measure electrical quantities. Measurement of electrical quantities may be done to measure electrical parameters of a system. Using transducers, physical properties such as temperature, pressure, flow, force

Electroanalytical methods measure the electric potential in volts and/or the electric current in amps in an electrochemical cell containing the analyte. [ 1 ] [ 2 ] These methods can be categorized according to which aspects of the cell are controlled and which are measured.
Combined with an internal voltage source, the current measuring mode can be adapted to measure very high resistances, of the order of 10 17 Ω. Finally, by calculation from the known capacitance of the electrometer's input terminal, the instrument can measure very small electric charges , down to a small fraction of a picocoulomb.
σ T is the electrical conductivity at the temperature T, σ T cal is the electrical conductivity at the calibration temperature T cal, α is the temperature compensation gradient of the solution. The temperature compensation gradient for most naturally occurring samples of water is about 2%/°C; however it can range between 1 and 3%/°C.
