The electric potential at any point in space made by a point charge Q is presented by the formula given below. It is the electric potential energy per unit charge. The electric potential at any point ...

This equation can be used to calculate what the output might be from a particular transformer, or to work out how to design a transformer to make a particular potential difference (pd) change: \(\frac ...

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 resistance of ...
