Yokogawa said its latest high-voltage, wide-bandwidth probe can stay on top of the faster switching speeds of next-generation ...

We can calculate the voltage across the thermistor under these conditions. First find the total resistance of the voltage divider. If the thermistor is moved to a freezer its resistance rises to ...

Laura is an assistant editor for The Scientist. She earned her PhD in biomedical sciences from Rush University by studying how circadian rhythms and alcohol affect the gut.

When resistors are connected in series, the total voltage (or potential difference) across all the resistors is equal to the sum of the voltages across each resistor. In other words, the voltages ...
