formula for determining potential difference
Electrically, V2-V1 (volts) where V2 and V1 are the electrical potentials at different points. Mechanically, mg(y2-y1) where m is mass, g is acceleration due to gravity, y =vertical position.
The whole circuit fails - because the action of the bulb blowing cuts the circuit.
The difference between a series and parallel circuit is that a series circuit is connected in such a way that the same current intensity flows through the elements while a parallel circuit is connected in such a way that the same potential appears across their terminals.
Current = (Voltage across the circuit) divided by (Total resistance of the circuit). The current is the same at every point in the series circuit.
The voltage divider circuit is a network of two or more components in series, often resistors, between a potential difference. The voltage between the components will be somewhere between the potential difference across the whole network and so divides the total voltage into one or more intermediate voltages.
series circuit can only move on one patha parallel circuit has two more paths for the electric carve to follow

In a parallel circuit, all the external resistors are supplied the same potential difference which is not possible in a series circuit. Also in a parallel circuit, every resistor or component can be individually turned on or off without affecting the rest of the circuit.
difference between series is one pathway through circuit,difference between parralal is more then one pathway through circuit.
A voltmeter is used to measure potential difference across two points in an electrical circuit . The voltmeter is connected in parallel across the circuit element (resistance ) so that its inclusion in the circuit has negligible effect on total resistance and current flowing in yhe circuit A voltmeter has high resistance,if connected in series it will increase of circuit and reduce the current in the circuit
The same current passes through all the devices, and the sum of the potential differences across the devices is equal to the terminal potential difference across the power supply.
Current = (Voltage across the circuit) divided by (Total resistance of the circuit). The current is the same at every point in the series circuit.
In series circuits current will be the same through out the circuit. So whereever we connect the ammeter the same current is registered. But in parallel circuit current will be different in different lines. In parallel circuits the potential difference will be the same but in series pd will be different.

The voltage between the components will be somewhere between the potential difference across the whole network and so divides the total voltage into one or more intermediate voltages.
current is constant in the series circuit. The resistances of the components add up and the potential differences is divided propotionally over the components depending on their resistances.
