ATTINY85 measuring internal voltage

How is it possible to have high voltage and low current? It seems to contradict the relationship between current and voltage in E=IR

How does a flame sensor or thermocouple operate with just one wire?

Excessively high temperature reading with LM35

What makes mains voltage safe in homes?

What are the highest DC and AC voltages or currents that can be considered as safe?

Could a modified sine wave inverter destroy/damage the AC adapter for a laptop?

Reducing voltage with resistors

How many LEDs can you chain in series?

9V battery and resistor are connected in series - the voltage across the resistor is < 9V. Why?
