This equation defines the relation between the concentrations of an ion on either side of a membrane that it perfectly selective for that ion and the potential difference (voltage) that will be ...

In some ways, the very term “voltage divider” explains itself. It refers to a simple, passive circuit in which multiple ...

Save guides, add subjects and pick up where you left off with your BBC account. The resistors in a potential divider can have fixed values, or one may be a variable component like an LDR (light ...

When resistors are connected in series, the total voltage (or potential difference ... of two resistors connected in parallel, this equation is used. \(\frac{1}{R}=\frac{1}{R}_{ ...
