Why are many resistors connected in Series or parallel instead of 1 Resistor having large resistance ?
- The total resistance in a parallel circuit is less than the smallest of the individual resistances.
- Each resistor in parallel has the same voltage of the source applied to it (voltage is constant in a parallel circuit).
- Parallel resistors do not each get the total current; they divide it (current is dependent on the value of each resistor and the number of total resistors in a circuit).
- single large resistors can be used ,but many resistors arranged in parallel or series can make things happen to convert voltage to current or current to voltage.
