The procedure is simple. Find pairs of resistors in the network that are in parallel or in series. Replace the pair with the equivalent resistance as defined by the equation for series or parallel resistors. Repeat the reduction process until a single equivalent resistance is found.

Changing the resistance

1. If you increase the number of lamps in a series circuit , there will be less current.
2. You could increase or decrease the resistance in a circuit by using a variable resistor .
3. The quantities voltage, current and resistance are linked by the relationship :
4. This relationship is called Ohm’s Law.

A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses.

In a parallel circuit, the voltage across each of the components is the same, and the total current is the sum of the currents flowing through each component. In a series circuit, every device must function for the circuit to be complete. If one bulb burns out in a series circuit, the entire circuit is broken.

Two bulbs in a simple parallel circuit each enjoy the full voltage of the battery. This is why the bulbs in the parallel circuit will be brighter than those in the series circuit. Another advantage to the parallel circuit is that if one loop is disconnected, then the other remains powered.

REVIEW: In a series circuit, all components are connected end-to-end, forming a single path for current flow. In a parallel circuit, all components are connected across each other, forming exactly two sets of electrically common points.

Advantages of Series Circuit The advantages of Series Circuits include: Easy to design and build the circuit. If a component breaks, the current flow stops. It acts as a current regulator. The cost to build a Series Circuit is less compared to Parallel Circuit.

When batteries are hooked up In series, the voltage is increased. For example, two – 6 Volt batteries connected in series produce 12 Volts. When batteries are hooked up in parallel, the voltage remains the same, but the power (or available current) is increased. This means that the batteries would last longer.
