Amps and volts are often used interchangeably to describe the potential power of an electrical system, leading to even more confusion about the difference between voltage and amperage.

When the thermistor is placed in a warm environment it has a resistance of \(100 \Omega\). We can calculate the voltage across the thermistor under these conditions. First find the total ...

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 ...
