## Which lasts longer batteries in series or parallel?

The answer is they last longer in parallel assuming that the batteries are very similar in type, age and size. However in most applications you don’t have much choice in what combination to use, because the voltage requirement dictates the number of batteries to use in series.

## What is the effect of increasing the number of batteries in a simple electric circuit?

When using batteries, increasing the voltage also increases the current in the circuit. An increase in the current is observed when the brightness of the bulb increases.

Will the current through the first resistor be equal to the voltage of the battery?

(b) The current through R1 can be found using Ohm’s law and the voltage applied. The current through R1 is equal to the current from the battery. The potential drop V1 across the resistor R1 (which represents the resistance in the connecting wires) can be found using Ohm’s law.

### What relationship appears to exist between the battery voltage and the individual voltage drops for a parallel circuit?

And the voltage drop across an individual branch in a parallel circuit is the equal to the battery voltage – 12 volts.

### What’s the difference between parallel and series batteries?

The main difference in wiring batteries in series vs. parallel is the impact on the output voltage and the capacity of the battery system. Batteries wired in series will have their voltages added together. Batteries wired in parallel will have their capacities (measured in amp-hours) added together.

Why are parallel circuits brighter than series?

Current is common in a series circuit. In a parallel circuit, voltage is common so each lamp in the circuit has the same voltage applied, thus the lamps in parallel are brighter than those in series.

## What is series circuit and parallel circuits?

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.
