Learn how to measure voltage and current in electrical circuits using voltmeters and ammeters. Discover why voltmeters are connected in parallel and ammeters in series.

Review the key terms and skills related to voltmeters and ammeters, including where to place them in a circuit.

Review the components of a circuit and their symbols such as battery, resistor, and switch. Analyze how the power of a resistor is related to the current and electric potential difference …

The actual voltage across the current source will emerge from the analysis of the surrounding circuit. If you need to label the voltage for some reason, it is usually done as shown in option …

Let's review the components of a circuit and their symbols such as battery, resistor, and switch.

Let's learn how to calculate current and voltage across each resistor in a circuit.

Discover how voltage remains constant between elements and how current remains constant throughout the circuit. Learn how resistors in series increase total resistance, and how to …

Galvanometers are for small currents (just detecting the presence of current), ammeters are for larger currents. Here we converted a really sensitive galvanometer into an ammeter that can …

Suppose you are building a circuit and you need a certain value resistor, say 500 ohms. What if you don't have that value resistor in your stock, and you don't have time to order from Digikey?

Discover how to solve complex circuit problems in physics by simplifying schematics, combining parallel resistors, and applying Ohm's law. Master the art of analyzing circuits with multiple …
