Power = voltage x current. The higher the power, the quicker the rate at which a battery can do work—this relationship shows how voltage and …

6.5: Electrical Measuring Instruments

Analog and Digital Meters You may encounter two types of meters in the physics lab: analog and digital. The term ''analog'' refers to signals or information represented by a continuously variable physical quantity, such as voltage or current. An analog meter uses a galvanometer, which is essentially a coil of wire with a small resistance, in a magnetic …

9.1 Electrical Current

Current in a Circuit In the previous paragraphs, we defined the current as the charge that flows through a cross-sectional area per unit time. In order for charge to flow through an appliance, such as the headlight shown in Figure 9.5, there must be a complete path (or circuit) from the positive terminal to the negative terminal. ...

OverviewCurrent density and Ohm''s lawSymbolConventionsOhm''s lawAlternating and direct currentOccurrencesMeasurement

Current density is the rate at which charge passes through a chosen unit area. It is defined as a vector whose magnitude is the current per unit cross-sectional area. As discussed in Reference direction, the direction is arbitrary. Conventionally, if the moving charges are positive, then the current density has the same sign as the velocity of the charges. For negative charges, the sign of the current density is opposite to the velocity of the charges. In SI units, current density (symbol: …
