A parallel circuit is way of connecting components on separate branches, so the current can take different routes around the circuit. The current is different in different parts of a parallel circuit.

Current is a measure of how much electric charge flows through a circuit. The more charge that flows, the bigger the current. Current is measured in amperes. The symbol for ampere is A. For example, ...

In Part 1 of the Electronics for Kids series, we looked at LEDs; in Part 2, we explored capacitors; and in Part 3, we took an in-depth look at electrical measurements. In this article, we will focus ...

What do series and parallel circuits have to do with Christmas lights? In this episode of Crash Course Physics, Shini walks us through the differences between series and parallel circuits and how that ...

To measure a zener diode’s breakdown voltage, you need a dc voltage source whose voltage exceeds that of the zener voltage. In Figure 1, resistor R SER provides voltage drop between V IN and V ZEN. In ...

Fig 1. Two multiplexers (U2 and U3) enable this data-acquisition IC (U1) to monitor up to 12 battery temperatures in a configuration that saves power when it isn’t actively making measurements. Fig 2.
