Question

Bulb in series vs parallel
With advantages and disadvantages​

Answer 1

Answer:

ower Sources in Series versus Parallel

An electrical source, such as a battery or power supply, creates a voltage difference across the circuit that drives electrical current. From Ohm's law, the greater the voltage, the greater the current. With batteries wired in series, the total voltage is the sum of the individual voltages. For instance, three 5-volt batteries in series produce a total of 15 volts. By contrast, the voltage for batteries in parallel do not add up, though their capacities do. This means if one 5-volt battery powers a circuit for two hours, two 5-volt batteries in parallel would last four hours, but supply only 5 volts total.

Resistors in Series versus Parallel

Resistors reduce the current that a circuit delivers to the device using the electrical power. This is necessary to protect current-sensitive components and regulate the current in the circuit. Resistance is measured in units called ohms. Much like the voltage of batteries, resistors that are wired in series yield added overall resistance. Three 2-ohm resistors wired in series give a total of 6 ohms of resistance.

Answer 2

Explanation:

consisting of a source of EMF and two resistors are connected in series we are interested in finding the resistance of the network lying between A and B that is what signal equivalent resistor are would have the same resistance as the two resistors link road because
